What is (are) Opitz G/BBB syndrome ? 
 Opitz G/BBB syndrome is a genetic condition that causes several abnormalities along the midline of the body. "G/BBB" represents the first letters of the last names of the families first diagnosed with this disorder and "Opitz" is the last name of the doctor who first described the signs and symptoms. There are two forms of Opitz G/BBB syndrome, X-linked Opitz G/BBB syndrome and autosomal dominant Opitz G/BBB syndrome. The two forms are distinguished by their genetic causes and patterns of inheritance. The signs and symptoms of the two forms are generally the same.  Nearly everyone with Opitz G/BBB syndrome has wide-spaced eyes (ocular hypertelorism). Affected individuals commonly have defects of the voice box (larynx), windpipe (trachea), or esophagus. These throat abnormalities can cause difficulty swallowing or breathing, in some cases resulting in recurrent pneumonia or life-threatening breathing problems. A common defect is a gap between the trachea and esophagus (laryngeal cleft) that allows food or fluids to enter the airway. The cleft can vary in size, and infants may struggle to breathe when feeding. Most males with Opitz G/BBB syndrome have genital abnormalities such as the urethra opening on the underside of the penis (hypospadias), undescended testes (cryptorchidism), an underdeveloped scrotum, or a scrotum divided into two lobes (bifid scrotum). These genital abnormalities can lead to problems in the urinary tract.  Mild intellectual disability and developmental delay occur in about 50 percent of people with Opitz G/BBB syndrome. Affected individuals have delayed motor skills, such as walking, speech delay, and learning difficulties. Some people with Opitz G/BBB syndrome have features of autistic spectrum disorders, which are characterized by impaired communication and socialization skills. About half of affected individuals also have an opening in the lip (cleft lip) with or without an opening in the roof of the mouth (cleft palate). Some have cleft palate without cleft lip. Less common features of Opitz G/BBB syndrome, affecting less than half of people with this disorder, include minor heart defects, an obstruction of the anal opening (imperforate anus), and brain defects such as a small or absent connection between the left and right halves of the brain (corpus callosum). Distinct facial features that may be seen in this disorder include a prominent forehead, widow's peak hairline, flat nasal bridge, thin upper lip, and low-set ears. These features vary among affected individuals, even within the same family.
How many people are affected by Opitz G/BBB syndrome ? 
 X-linked Opitz G/BBB syndrome is thought to affect 1 in 10,000 to 50,000 males, although it is likely that this condition is underdiagnosed.  The incidence of autosomal dominant Opitz G/BBB syndrome is unknown. It is part of a larger condition known as 22q11.2 deletion syndrome, which is estimated to affect 1 in 4,000 people.
What are the genetic changes related to Opitz G/BBB syndrome ? 
 X-linked Opitz G/BBB syndrome is caused by mutations in the MID1 gene. The MID1 gene provides instructions for making a protein called midline-1. This protein attaches (binds) to microtubules, which are rigid, hollow fibers that make up the cell's structural framework (the cytoskeleton). Microtubules help cells maintain their shape, assist in the process of cell division, and are essential for the movement of cells (cell migration). Midline-1 assists in recycling certain proteins that need to be reused instead of broken down. MID1 gene mutations lead to a decrease in midline-1 function, which prevents protein recycling. The resulting accumulation of proteins impairs microtubule function, leading to problems with cell division and migration. It is unclear how these changes disrupt normal development and cause the signs and symptoms of Opitz G/BBB syndrome.  Autosomal dominant Opitz G/BBB syndrome is caused by changes in chromosome 22. Some affected individuals have a deletion of a small piece of chromosome 22, specifically at an area of the chromosome designated 22q11.2. Because this same region is deleted in another condition called 22q11.2 deletion syndrome, researchers often consider Opitz/GBBB syndrome caused by this genetic change to be a form of 22q11.2 deletion syndrome. It is not known which of the deleted genes contribute to the signs and symptoms of Opitz G/BBB syndrome.  In other people, autosomal dominant Opitz/GBBB syndrome is caused by a mutation in the SPECC1L gene, which is near the 22q11.2 region but is not in the area that is typically deleted in other individuals with autosomal dominant Opitz G/BBB syndrome or 22q11.2 deletion syndrome. The SPECC1L gene provides instructions for making a protein called cytospin-A. This protein interacts with components of the cytoskeleton and stabilizes microtubules, which is necessary for these fibers to regulate various cell processes including the movement of cells to their proper location (cell migration). Cytospin-A is particularly involved in the migration of cells that will form the facial features. Mutations in the SPECC1L gene result in the production of a protein with a decreased ability to interact with components of the cytoskeleton. As a result, microtubules are disorganized and cells have trouble migrating to their proper location. Because the SPECC1L gene plays a role in facial development, mutations in this gene likely account for the cleft lip and palate seen in some individuals with Opitz G/BBB syndrome, but it is unclear how SPECC1L gene mutations cause the other features of this disorder.  Some people with Opitz G/BBB syndrome do not have any of the genetic changes described above. The cause of the condition in these individuals is unknown.
Is Opitz G/BBB syndrome inherited ? 
 When caused by mutations in the MID1 gene, Opitz G/BBB syndrome has an X-linked pattern of inheritance. It is considered X-linked because the MID1 gene is located on the X chromosome, one of the two sex chromosomes in each cell. In males, who have only one X chromosome, a mutation in the only copy of the gene in each cell is sufficient to cause the condition. In females, who have two copies of the X chromosome, one altered copy of the gene in each cell can lead to less severe features of the condition or may cause no symptoms at all. Because it is unlikely that females will have two altered copies of the MID1 gene, females with X-linked Opitz G/BBB syndrome typically have hypertelorism as the only sign of the disorder. A characteristic of X-linked inheritance is that fathers cannot pass X-linked traits to their sons.  Rarely, Opitz G/BBB syndrome is inherited in an autosomal dominant pattern, which means one copy of the altered gene in each cell is sufficient to cause the disorder. These cases are caused by a mutation in the SPECC1L gene or by a deletion of genetic material from one copy of chromosome 22 in each cell. Males and females with autosomal dominant Opitz G/BBB syndrome usually have the same severity of symptoms.  In both types of Opitz G/BBB syndrome, some affected people inherit the genetic change from an affected parent. Other cases may result from new mutations. These cases occur in people with no history of the disorder in their family.

What is (are) Stickler syndrome ? 
 Stickler syndrome is a group of hereditary conditions characterized by a distinctive facial appearance, eye abnormalities, hearing loss, and joint problems. These signs and symptoms vary widely among affected individuals.  A characteristic feature of Stickler syndrome is a somewhat flattened facial appearance. This appearance results from underdeveloped bones in the middle of the face, including the cheekbones and the bridge of the nose. A particular group of physical features called Pierre Robin sequence is also common in people with Stickler syndrome. Pierre Robin sequence includes an opening in the roof of the mouth (a cleft palate), a tongue that is placed further back than normal (glossoptosis), and a small lower jaw (micrognathia). This combination of features can lead to feeding problems and difficulty breathing.  Many people with Stickler syndrome have severe nearsightedness (high myopia). In some cases, the clear gel that fills the eyeball (the vitreous) has an abnormal appearance, which is noticeable during an eye examination. Other eye problems are also common, including increased pressure within the eye (glaucoma), clouding of the lens of the eyes (cataracts), and tearing of the lining of the eye (retinal detachment). These eye abnormalities cause impaired vision or blindness in some cases.  In people with Stickler syndrome, hearing loss varies in degree and may become more severe over time. The hearing loss may be sensorineural, meaning that it results from changes in the inner ear, or conductive, meaning that it is caused by abnormalities of the middle ear.  Most people with Stickler syndrome have skeletal abnormalities that affect the joints. The joints of affected children and young adults may be loose and very flexible (hypermobile), though joints become less flexible with age. Arthritis often appears early in life and may cause joint pain or stiffness. Problems with the bones of the spine (vertebrae) can also occur, including abnormal curvature of the spine (scoliosis or kyphosis) and flattened vertebrae (platyspondyly). These spinal abnormalities may cause back pain.  Researchers have described several types of Stickler syndrome, which are distinguished by their genetic causes and their patterns of signs and symptoms. In particular, the eye abnormalities and severity of hearing loss differ among the types. Type I has the highest risk of retinal detachment. Type II also includes eye abnormalities, but type III does not (and is often called non-ocular Stickler syndrome). Types II and III are more likely than type I to have significant hearing loss. Types IV, V, and VI are very rare and have each been diagnosed in only a few individuals.  A condition similar to Stickler syndrome, called Marshall syndrome, is characterized by a distinctive facial appearance, eye abnormalities, hearing loss, and early-onset arthritis. Marshall syndrome can also include short stature. Some researchers have classified Marshall syndrome as a variant of Stickler syndrome, while others consider it to be a separate disorder.
How many people are affected by Stickler syndrome ? 
 Stickler syndrome affects an estimated 1 in 7,500 to 9,000 newborns. Type I is the most common form of the condition.
What are the genetic changes related to Stickler syndrome ? 
 Mutations in several genes cause the different types of Stickler syndrome. Between 80 and 90 percent of all cases are classified as type I and are caused by mutations in the COL2A1 gene. Another 10 to 20 percent of cases are classified as type II and result from mutations in the COL11A1 gene. Marshall syndrome, which may be a variant of Stickler syndrome, is also caused by COL11A1 gene mutations. Stickler syndrome types III through VI result from mutations in other, related genes.  All of the genes associated with Stickler syndrome provide instructions for making components of collagens, which are complex molecules that give structure and strength to the connective tissues that support the body's joints and organs. Mutations in any of these genes impair the production, processing, or assembly of collagen molecules. Defective collagen molecules or reduced amounts of collagen impair the development of connective tissues in many different parts of the body, leading to the varied features of Stickler syndrome.  Not all individuals with Stickler syndrome have mutations in one of the known genes. Researchers believe that mutations in other genes may also cause this condition, but those genes have not been identified.
Is Stickler syndrome inherited ? 
 Stickler syndrome types I, II, and III are inherited in an autosomal dominant pattern, which means one copy of the altered gene in each cell is sufficient to cause the disorder. In some cases, an affected person inherits a gene mutation from one affected parent. Other cases result from new mutations. These cases occur in people with no history of Stickler syndrome in their family.  Marshall syndrome also typically has an autosomal dominant pattern of inheritance.  Stickler syndrome types IV, V, and VI are inherited in an autosomal recessive pattern. Autosomal recessive inheritance means both copies of the gene in each cell have mutations. The parents of an individual with an autosomal recessive condition each carry one copy of the mutated gene, but they typically do not show signs and symptoms of the condition.

What is (are) mucolipidosis III alpha/beta ? 
 Mucolipidosis III alpha/beta is a slowly progressive disorder that affects many parts of the body. Signs and symptoms of this condition typically appear around age 3.  Individuals with mucolipidosis III alpha/beta grow slowly and have short stature. They also have stiff joints and dysostosis multiplex, which refers to multiple skeletal abnormalities seen on x-ray. Many affected individuals develop low bone mineral density (osteoporosis), which weakens the bones and makes them prone to fracture. Osteoporosis and progressive joint problems also cause bone pain that becomes more severe over time in people with mucolipidosis III alpha/beta.  People with mucolipidosis III alpha/beta often have heart valve abnormalities and mild clouding of the clear covering of the eye (cornea). Their facial features become slightly thickened or "coarse" over time. Affected individuals may also develop frequent ear and respiratory infections. About half of people with this condition have mild intellectual disability or learning problems. Individuals with mucolipidosis III alpha/beta generally survive into adulthood, but they may have a shortened lifespan.
How many people are affected by mucolipidosis III alpha/beta ? 
 Mucolipidosis III alpha/beta is a rare disorder, although its exact prevalence is unknown. It is estimated to occur in about 1 in 100,000 to 400,000 individuals worldwide.
What are the genetic changes related to mucolipidosis III alpha/beta ? 
 Mutations in the GNPTAB gene cause mucolipidosis III alpha/beta. This gene provides instructions for making a part (subunit) of an enzyme called GlcNAc-1-phosphotransferase. This enzyme helps prepare certain newly made enzymes for transport to lysosomes. Lysosomes are compartments within the cell that use digestive enzymes to break down large molecules into smaller ones that can be reused by cells. GlcNAc-1-phosphotransferase is involved in the process of attaching a molecule called mannose-6-phosphate (M6P) to specific digestive enzymes. Just as luggage is tagged at the airport to direct it to the correct destination, enzymes are often "tagged" after they are made so they get to where they are needed in the cell. M6P acts as a tag that indicates a digestive enzyme should be transported to the lysosome.  Mutations in the GNPTAB gene that cause mucolipidosis III alpha/beta result in reduced activity of GlcNAc-1-phosphotransferase. These mutations disrupt the tagging of digestive enzymes with M6P, which prevents many enzymes from reaching the lysosomes. Digestive enzymes that do not receive the M6P tag end up outside the cell, where they have increased activity. The shortage of digestive enzymes within lysosomes causes large molecules to accumulate there. Conditions that cause molecules to build up inside lysosomes, including mucolipidosis III alpha/beta, are called lysosomal storage disorders. The signs and symptoms of mucolipidosis III alpha/beta are most likely due to the shortage of digestive enzymes inside lysosomes and the effects these enzymes have outside the cell.  Mutations in the GNPTAB gene can also cause a similar but more severe disorder called mucolipidosis II alpha/beta. These mutations completely eliminate the function of GlcNAc-1-phosphotransferase. Mucolipidosis III alpha/beta and mucolipidosis II alpha/beta represent two ends of a spectrum of disease severity.
Is mucolipidosis III alpha/beta inherited ? 
 This condition is inherited in an autosomal recessive pattern, which means both copies of the gene in each cell have mutations. The parents of an individual with an autosomal recessive condition each carry one copy of the mutated gene, but they typically do not show signs and symptoms of the condition.

What is (are) Hashimoto thyroiditis ? 
 Hashimoto thyroiditis is a condition that affects the function of the thyroid, which is a butterfly-shaped gland in the lower neck. The thyroid makes hormones that help regulate a wide variety of critical body functions. For example, thyroid hormones influence growth and development, body temperature, heart rate, menstrual cycles, and weight. Hashimoto thyroiditis is a form of chronic inflammation that can damage the thyroid, reducing its ability to produce hormones.  One of the first signs of Hashimoto thyroiditis is an enlargement of the thyroid called a goiter. Depending on its size, the enlarged thyroid can cause the neck to look swollen and may interfere with breathing and swallowing. As damage to the thyroid continues, the gland can shrink over a period of years and the goiter may eventually disappear.  Other signs and symptoms resulting from an underactive thyroid can include excessive tiredness (fatigue), weight gain or difficulty losing weight, hair that is thin and dry, a slow heart rate, joint or muscle pain, and constipation. People with this condition may also have a pale, puffy face and feel cold even when others around them are warm. Affected women can have heavy or irregular menstrual periods and difficulty conceiving a child (impaired fertility). Difficulty concentrating and depression can also be signs of a shortage of thyroid hormones.  Hashimoto thyroiditis usually appears in mid-adulthood, although it can occur earlier or later in life. Its signs and symptoms tend to develop gradually over months or years.
How many people are affected by Hashimoto thyroiditis ? 
 Hashimoto thyroiditis affects 1 to 2 percent of people in the United States. It occurs more often in women than in men, which may be related to hormonal factors. The condition is the most common cause of thyroid underactivity (hypothyroidism) in the United States.
What are the genetic changes related to Hashimoto thyroiditis ? 
 Hashimoto thyroiditis is thought to result from a combination of genetic and environmental factors. Some of these factors have been identified, but many remain unknown.  Hashimoto thyroiditis is classified as an autoimmune disorder, one of a large group of conditions that occur when the immune system attacks the body's own tissues and organs. In people with Hashimoto thyroiditis, white blood cells called lymphocytes accumulate abnormally in the thyroid, which can damage it. The lymphocytes make immune system proteins called antibodies that attack and destroy thyroid cells. When too many thyroid cells become damaged or die, the thyroid can no longer make enough hormones to regulate body functions. This shortage of thyroid hormones underlies the signs and symptoms of Hashimoto thyroiditis. However, some people with thyroid antibodies never develop hypothyroidism or experience any related signs or symptoms.  People with Hashimoto thyroiditis have an increased risk of developing other autoimmune disorders, including vitiligo, rheumatoid arthritis, Addison disease, type 1 diabetes, multiple sclerosis, and pernicious anemia.  Variations in several genes have been studied as possible risk factors for Hashimoto thyroiditis. Some of these genes are part of a family called the human leukocyte antigen (HLA) complex. The HLA complex helps the immune system distinguish the body's own proteins from proteins made by foreign invaders (such as viruses and bacteria). Other genes that have been associated with Hashimoto thyroiditis help regulate the immune system or are involved in normal thyroid function. Most of the genetic variations that have been discovered are thought to have a small impact on a person's overall risk of developing this condition.  Other, nongenetic factors also play a role in Hashimoto thyroiditis. These factors may trigger the condition in people who are at risk, although the mechanism is unclear. Potential triggers include changes in sex hormones (particularly in women), viral infections, certain medications, exposure to ionizing radiation, and excess consumption of iodine (a substance involved in thyroid hormone production).
Is Hashimoto thyroiditis inherited ? 
 The inheritance pattern of Hashimoto thyroiditis is unclear because many genetic and environmental factors appear to be involved. However, the condition can cluster in families, and having a close relative with Hashimoto thyroiditis or another autoimmune disorder likely increases a person's risk of developing the condition.
