user: What are the genetic changes related to Hashimoto thyroiditis ?

assistant: 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).
user: Is Hashimoto thyroiditis inherited ?

assistant: 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.

user: What is (are) cutis laxa ?

assistant: Cutis laxa is a disorder of connective tissue, which is the tissue that forms the body's supportive framework. Connective tissue provides structure and strength to the muscles, joints, organs, and skin.  The term "cutis laxa" is Latin for loose or lax skin, and this condition is characterized by skin that is sagging and not stretchy (inelastic). The skin often hangs in loose folds, causing the face and other parts of the body to have a droopy appearance. Extremely wrinkled skin may be particularly noticeable on the neck and in the armpits and groin.  Cutis laxa can also affect connective tissue in other parts of the body, including the heart, blood vessels, joints, intestines, and lungs. The disorder can cause heart problems and abnormal narrowing, bulging, or tearing of critical arteries. Affected individuals may have soft out-pouchings in the lower abdomen (inguinal hernia) or around the belly button (umbilical hernia). Pouches called diverticula can also develop in the walls of certain organs, such as the bladder and intestines. During childhood, some people with cutis laxa develop a lung disease called emphysema, which can make it difficult to breathe. Depending on which organs and tissues are affected, the signs and symptoms of cutis laxa can range from mild to life-threatening.  Researchers have described several different forms of cutis laxa. The forms are often distinguished by their pattern of inheritance: autosomal dominant, autosomal recessive, or X-linked. In general, the autosomal recessive forms of cutis laxa tend to be more severe than the autosomal dominant form. In addition to the features described above, some people with autosomal recessive cutis laxa have delayed development, intellectual disability, seizures, and problems with movement that can worsen over time.  The X-linked form of cutis laxa is often called occipital horn syndrome. This form of the disorder is considered a mild type of Menkes syndrome, which is a condition that affects copper levels in the body. In addition to sagging and inelastic skin, occipital horn syndrome is characterized by wedge-shaped calcium deposits in a bone at the base of the skull (the occipital bone), coarse hair, and loose joints.
user: How many people are affected by cutis laxa ?

assistant: Cutis laxa is a rare disorder. About 200 affected families worldwide have been reported.
user: What are the genetic changes related to cutis laxa ?

assistant: Cutis laxa can be caused by mutations in the ATP6V0A2, ATP7A, EFEMP2, ELN, or FBLN5 gene. Most of these genes are involved in the formation and function of elastic fibers, which are slender bundles of proteins that provide strength and flexibility to connective tissue throughout the body. Elastic fibers allow the skin to stretch, the lungs to expand and contract, and arteries to handle blood flowing through them at high pressure.  The major component of elastic fibers, a protein called elastin, is produced from the ELN gene. Other proteins that appear to have critical roles in the assembly of elastic fibers are produced from the EFEMP2, FBLN5, and ATP6V0A2 genes. Mutations in any of these genes disrupt the formation, assembly, or function of elastic fibers. A shortage of these fibers weakens connective tissue in the skin, arteries, lungs, and other organs. These defects in connective tissue underlie the major features of cutis laxa.  Occipital horn syndrome is caused by mutations in the ATP7A gene. This gene provides instructions for making a protein that is important for regulating copper levels in the body. Mutations in the ATP7A gene result in poor distribution of copper to the body's cells. A reduced supply of copper can decrease the activity of numerous copper-containing enzymes that are necessary for the structure and function of bone, skin, hair, blood vessels, and the nervous system. The signs and symptoms of occipital horn syndrome are caused by the reduced activity of these copper-containing enzymes.  Mutations in the genes described above account for only a small percentage of all cases of cutis laxa. Researchers suspect that mutations in other genes, which have not been identified, can also be responsible for the condition.  Rare cases of cutis laxa are acquired, which means they are probably not caused by inherited gene mutations. Acquired cutis laxa appears later in life and is related to the destruction of normal elastic fibers. The causes of acquired cutis laxa are unclear, although it may occur as a side effect of treatment with medications that remove copper from the body (copper chelating drugs).
user: Is cutis laxa inherited ?

assistant: Cutis laxa can have an autosomal dominant, autosomal recessive, or X-linked recessive pattern of inheritance.  When cutis laxa is caused by ELN mutations, it has an autosomal dominant inheritance pattern. Autosomal dominant inheritance means one copy of the altered gene in each cell is sufficient to cause the disorder. Rarely, cases of cutis laxa resulting from FBLN5 mutations can also have an autosomal dominant pattern of inheritance.  Researchers have described at least two forms of autosomal recessive cutis laxa. Type I results from mutations in the EFEMP2 or FBLN5 gene, while type II is caused by mutations in the ATP6V02 gene. 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.  Occipital horn syndrome has an X-linked recessive pattern of inheritance. It results from mutations in the ATP7A gene, which is located on the X chromosome. The X chromosome is one of the two sex chromosomes. In males (who have only one X chromosome), one altered copy of the gene in each cell is sufficient to cause the condition. In females (who have two X chromosomes), a mutation would have to occur in both copies of the gene to cause the disorder. Because it is unlikely that females will have two altered copies of this gene, males are affected by X-linked recessive disorders much more frequently than females. A characteristic of X-linked inheritance is that fathers cannot pass X-linked traits to their sons.

user: What is (are) oculocutaneous albinism ?

assistant: Oculocutaneous albinism is a group of conditions that affect coloring (pigmentation) of the skin, hair, and eyes. Affected individuals typically have very fair skin and white or light-colored hair. Long-term sun exposure greatly increases the risk of skin damage and skin cancers, including an aggressive form of skin cancer called melanoma, in people with this condition. Oculocutaneous albinism also reduces pigmentation of the colored part of the eye (the iris) and the light-sensitive tissue at the back of the eye (the retina). People with this condition usually have vision problems such as reduced sharpness; rapid, involuntary eye movements (nystagmus); and increased sensitivity to light (photophobia).  Researchers have identified multiple types of oculocutaneous albinism, which are distinguished by their specific skin, hair, and eye color changes and by their genetic cause. Oculocutaneous albinism type 1 is characterized by white hair, very pale skin, and light-colored irises. Type 2 is typically less severe than type 1; the skin is usually a creamy white color and hair may be light yellow, blond, or light brown. Type 3 includes a form of albinism called rufous oculocutaneous albinism, which usually affects dark-skinned people. Affected individuals have reddish-brown skin, ginger or red hair, and hazel or brown irises. Type 3 is often associated with milder vision abnormalities than the other forms of oculocutaneous albinism. Type 4 has signs and symptoms similar to those seen with type 2.  Several additional types of this disorder have been proposed, each affecting one or a few families.
user: How many people are affected by oculocutaneous albinism ?

assistant: Overall, an estimated 1 in 20,000 people worldwide are born with oculocutaneous albinism. The condition affects people in many ethnic groups and geographical regions. Types 1 and 2 are the most common forms of this condition; types 3 and 4 are less common. Type 2 occurs more frequently in African Americans, some Native American groups, and people from sub-Saharan Africa. Type 3, specifically rufous oculocutaneous albinism, has been described primarily in people from southern Africa. Studies suggest that type 4 occurs more frequently in the Japanese and Korean populations than in people from other parts of the world.
user: What are the genetic changes related to oculocutaneous albinism ?

assistant: Oculocutaneous albinism can result from mutations in several genes, including TYR, OCA2, TYRP1, and SLC45A2. Changes in the TYR gene cause type 1; mutations in the OCA2 gene are responsible for type 2; TYRP1 mutations cause type 3; and changes in the SLC45A2 gene result in type 4. Mutations in additional genes likely underlie the other forms of this disorder. The genes associated with oculocutaneous albinism are involved in producing a pigment called melanin, which is the substance that gives skin, hair, and eyes their color. In the retina, melanin also plays a role in normal vision. Mutations in any of these genes disrupt the ability of cells to make melanin, which reduces pigmentation in the skin, hair, and eyes. A lack of melanin in the retina leads to the vision problems characteristic of oculocutaneous albinism.  Alterations in the MC1R gene can change the appearance of people with oculocutaneous albinism type 2. This gene helps regulate melanin production and is responsible for some normal variation in pigmentation. People with genetic changes in both the OCA2 and MC1R genes have many of the usual features of oculocutaneous albinism type 2, including light-colored eyes and vision problems; however, they typically have red hair instead of the usual yellow, blond, or light brown hair seen with this condition.  Some individuals with oculocutaneous albinism do not have mutations in any of the known genes. In these people, the genetic cause of the condition is unknown.
user: Is oculocutaneous albinism inherited ?

assistant: Oculocutaneous albinism is inherited in an autosomal recessive pattern, which means both copies of a gene in each cell have mutations. Most often, the parents of an individual with an autosomal recessive condition each carry one copy of the mutated gene, but they do not show signs and symptoms of the condition.

user: What is (are) Saethre-Chotzen syndrome ?

assistant: Saethre-Chotzen syndrome is a genetic condition characterized by the premature fusion of certain skull bones (craniosynostosis). This early fusion prevents the skull from growing normally and affects the shape of the head and face.  Most people with Saethre-Chotzen syndrome have prematurely fused skull bones along the coronal suture, the growth line that goes over the head from ear to ear. Other parts of the skull may be malformed as well. These changes can result in an abnormally shaped head, a high forehead, a low frontal hairline, droopy eyelids (ptosis), widely spaced eyes, and a broad nasal bridge. One side of the face may appear noticeably different from the other (facial asymmetry). Most people with Saethre-Chotzen syndrome also have small, unusually shaped ears.  The signs and symptoms of Saethre-Chotzen syndrome vary widely, even among affected individuals in the same family. This condition can cause mild abnormalities of the hands and feet, such as fusion of the skin between the second and third fingers on each hand and a broad or duplicated first (big) toe. Delayed development and learning difficulties have been reported, although most people with this condition are of normal intelligence. Less common signs and symptoms of Saethre-Chotzen syndrome include short stature, abnormalities of the bones of the spine (the vertebra), hearing loss, and heart defects.  Robinow-Sorauf syndrome is a condition with features similar to those of Saethre-Chotzen syndrome, including craniosynostosis and broad or duplicated great toes. It was once considered a separate disorder, but was found to result from mutations in the same gene and is now thought to be a mild variant of Saethre-Chotzen syndrome.
user: How many people are affected by Saethre-Chotzen syndrome ?

assistant: Saethre-Chotzen syndrome has an estimated prevalence of 1 in 25,000 to 50,000 people.
user: What are the genetic changes related to Saethre-Chotzen syndrome ?

assistant: Mutations in the TWIST1 gene cause Saethre-Chotzen syndrome. The TWIST1 gene provides instructions for making a protein that plays an important role in early development. This protein is a transcription factor, which means that it attaches (binds) to specific regions of DNA and helps control the activity of particular genes. The TWIST1 protein is active in cells that give rise to bones, muscles, and other tissues in the head and face. It is also involved in the development of the limbs.  Mutations in the TWIST1 gene prevent one copy of the gene in each cell from making any functional protein. A shortage of the TWIST1 protein affects the development and maturation of cells in the skull, face, and limbs. These abnormalities underlie the signs and symptoms of Saethre-Chotzen syndrome, including the premature fusion of certain skull bones.  A small number of cases of Saethre-Chotzen syndrome have resulted from a structural chromosomal abnormality, such as a deletion or rearrangement of genetic material, in the region of chromosome 7 that contains the TWIST1 gene. When Saethre-Chotzen syndrome is caused by a chromosomal deletion instead of a mutation within the TWIST1 gene, affected children are much more likely to have intellectual disability, developmental delay, and learning difficulties. These features are typically not seen in classic cases of Saethre-Chotzen syndrome. Researchers believe that a loss of other genes on chromosome 7 may be responsible for these additional features.
user: Is Saethre-Chotzen syndrome inherited ?

assistant: This condition is 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 the mutation from one affected parent. Other cases may result from new mutations in the gene. These cases occur in people with no history of the disorder in their family.  Some people with a TWIST1 mutation do not have any of the obvious features of Saethre-Chotzen syndrome. These people are still at risk of passing on the gene mutation and may have a child with craniosynostosis and the other typical signs and symptoms of the condition.

user: What is (are) VLDLR-associated cerebellar hypoplasia ?

assistant: VLDLR-associated cerebellar hypoplasia is an inherited condition that affects the development of the brain. People with this condition have an unusually small and underdeveloped cerebellum, which is the part of the brain that coordinates movement. This brain malformation leads to problems with balance and coordination (ataxia) that become apparent in infancy and remain stable over time. Children with VLDLR-associated cerebellar hypoplasia may learn to walk later in childhood, usually after the age of 6, although some are never able to walk independently. In one Turkish family, affected people walk on their hands and feet (quadrupedal locomotion).  Additional features of VLDLR-associated cerebellar hypoplasia include moderate to profound intellectual disability, impaired speech (dysarthria) or a lack of speech, and eyes that do not look in the same direction (strabismus). Some affected individuals have also had flat feet (pes planus), seizures, and short stature. Studies suggest that VLDLR-associated cerebellar hypoplasia does not significantly affect a person's life expectancy.
user: How many people are affected by VLDLR-associated cerebellar hypoplasia ?

assistant: VLDLR-associated cerebellar hypoplasia is rare; its prevalence is unknown. The condition was first described in the Hutterite population in Canada and the United States. This condition has also been reported in families from Iran and Turkey.
user: What are the genetic changes related to VLDLR-associated cerebellar hypoplasia ?

assistant: As its name suggests, VLDLR-associated cerebellar hypoplasia results from mutations in the VLDLR gene. This gene provides instructions for making a protein called a very low density lipoprotein (VLDL) receptor. Starting before birth, this protein plays a critical role in guiding the movement of developing nerve cells to their appropriate locations in the brain. Mutations in the VLDLR gene prevent cells from producing any functional VLDL receptor protein. Without this protein, developing nerve cells cannot reach the parts of the brain where they are needed. The resulting problems with brain development lead to ataxia and the other major features of this condition.
user: Is VLDLR-associated cerebellar hypoplasia inherited ?

assistant: 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.
