Topic: Dowling-Degos disease
Question: What are the genetic changes related to Dowling-Degos disease ?
Answer: Mutations in the KRT5 gene cause Dowling-Degos disease. The KRT5 gene provides instructions for making a protein called keratin 5. Keratins are a family of proteins that form the structural framework of certain cells, particularly cells that make up the skin, hair, and nails. Keratin 5 is produced in cells called keratinocytes found in the outer layer of the skin (the epidermis). Keratin 5 is one component of molecules called keratin intermediate filaments. These filaments assemble into strong networks that help attach keratinocytes together and anchor the epidermis to underlying layers of skin. Researchers believe that keratin 5 may also play a role in transporting melanosomes, which are cellular structures that produce a pigment called melanin. The transport of these structures into keratinocytes is important for normal skin coloration (pigmentation).  KRT5 gene mutations that cause Dowling-Degos disease lead to a decrease in the amount of functional keratin 5 protein that is produced. A reduction in keratin 5 can impair the formation of keratin intermediate filaments. As a result, the normal organization of the epidermis is altered, leading to the development of different types of skin lesions. Additionally, a decrease in keratin 5 may disrupt the movement of pigment-carrying melanosomes into keratinocytes, where they are needed for normal skin pigmentation. This disruption of melanosome transport is thought to cause the pigmentation abnormalities seen in individuals with Dowling-Degos disease.  Some people with Dowling-Degos disease do not have an identified mutation in the KRT5 gene. In these cases, the cause of the condition is unknown.

Topic: Sandhoff disease
Question: What is (are) Sandhoff disease ?
Answer: Sandhoff disease is a rare inherited disorder that progressively destroys nerve cells (neurons) in the brain and spinal cord.  The most common and severe form of Sandhoff disease becomes apparent in infancy. Infants with this disorder typically appear normal until the age of 3 to 6 months, when their development slows and muscles used for movement weaken. Affected infants lose motor skills such as turning over, sitting, and crawling. They also develop an exaggerated startle reaction to loud noises. As the disease progresses, children with Sandhoff disease experience seizures, vision and hearing loss, intellectual disability, and paralysis. An eye abnormality called a cherry-red spot, which can be identified with an eye examination, is characteristic of this disorder. Some affected children also have enlarged organs (organomegaly) or bone abnormalities. Children with the severe infantile form of Sandhoff disease usually live only into early childhood.  Other forms of Sandhoff disease are very rare. Signs and symptoms can begin in childhood, adolescence, or adulthood and are usually milder than those seen with the infantile form. Characteristic features include muscle weakness, loss of muscle coordination (ataxia) and other problems with movement, speech problems, and mental illness. These signs and symptoms vary widely among people with late-onset forms of Sandhoff disease.

Question: What are the genetic changes related to Sandhoff disease ?
Answer: Mutations in the HEXB gene cause Sandhoff disease. The HEXB gene provides instructions for making a protein that is part of two critical enzymes in the nervous system, beta-hexosaminidase A and beta-hexosaminidase B. These enzymes are located in lysosomes, which are structures in cells that break down toxic substances and act as recycling centers. Within lysosomes, these enzymes break down fatty substances, complex sugars, and molecules that are linked to sugars. In particular, beta-hexosaminidase A helps break down a fatty substance called GM2 ganglioside.  Mutations in the HEXB gene disrupt the activity of beta-hexosaminidase A and beta-hexosaminidase B, which prevents these enzymes from breaking down GM2 ganglioside and other molecules. As a result, these compounds can accumulate to toxic levels, particularly in neurons of the brain and spinal cord. A buildup of GM2 ganglioside leads to the progressive destruction of these neurons, which causes many of the signs and symptoms of Sandhoff disease.  Because Sandhoff disease impairs the function of lysosomal enzymes and involves the buildup of GM2 ganglioside, this condition is sometimes referred to as a lysosomal storage disorder or a GM2-gangliosidosis.

Topic: dihydrolipoamide dehydrogenase deficiency
Question: What is (are) dihydrolipoamide dehydrogenase deficiency ?
Answer: Dihydrolipoamide dehydrogenase deficiency is a severe condition that can affect several body systems. Signs and symptoms of this condition usually appear shortly after birth, and they can vary widely among affected individuals.  A common feature of dihydrolipoamide dehydrogenase deficiency is a potentially life-threatening buildup of lactic acid in tissues (lactic acidosis), which can cause nausea, vomiting, severe breathing problems, and an abnormal heartbeat. Neurological problems are also common in this condition; the first symptoms in affected infants are often decreased muscle tone (hypotonia) and extreme tiredness (lethargy). As the problems worsen, affected infants can have difficulty feeding, decreased alertness, and seizures. Liver problems can also occur in dihydrolipoamide dehydrogenase deficiency, ranging from an enlarged liver (hepatomegaly) to life-threatening liver failure. In some affected people, liver disease, which can begin anytime from infancy to adulthood, is the primary symptom. The liver problems are usually associated with recurrent vomiting and abdominal pain. Rarely, people with dihydrolipoamide dehydrogenase deficiency experience weakness of the muscles used for movement (skeletal muscles), particularly during exercise; droopy eyelids; or a weakened heart muscle (cardiomyopathy). Other features of this condition include excess ammonia in the blood (hyperammonemia), a buildup of molecules called ketones in the body (ketoacidosis), or low blood sugar levels (hypoglycemia).  Typically, the signs and symptoms of dihydrolipoamide dehydrogenase deficiency occur in episodes that may be triggered by fever, injury, or other stresses on the body. Affected individuals are usually symptom-free between episodes. Many infants with this condition do not survive the first few years of life because of the severity of these episodes. Affected individuals who survive past early childhood often have delayed growth and neurological problems, including intellectual disability, muscle stiffness (spasticity), difficulty coordinating movements (ataxia), and seizures.

Topic: dihydrolipoamide dehydrogenase deficiency
Question: What are the genetic changes related to dihydrolipoamide dehydrogenase deficiency ?
Answer: Mutations in the DLD gene cause dihydrolipoamide dehydrogenase deficiency. This gene provides instructions for making an enzyme called dihydrolipoamide dehydrogenase (DLD). DLD is one component of three different groups of enzymes that work together (enzyme complexes): branched-chain alpha-keto acid dehydrogenase (BCKD), pyruvate dehydrogenase (PDH), and alpha ()-ketoglutarate dehydrogenase (KGDH). The BCKD enzyme complex is involved in the breakdown of three protein building blocks (amino acids) commonly found in protein-rich foods: leucine, isoleucine, and valine. Breakdown of these amino acids produces molecules that can be used for energy. The PDH and KGDH enzyme complexes are involved in other reactions in the pathways that convert the energy from food into a form that cells can use.  Mutations in the DLD gene impair the function of the DLD enzyme, which prevents the three enzyme complexes from functioning properly. As a result, molecules that are normally broken down and their byproducts build up in the body, damaging tissues and leading to lactic acidosis and other chemical imbalances. In addition, the production of cellular energy is diminished. The brain is especially affected by the buildup of molecules and the lack of cellular energy, resulting in the neurological problems associated with dihydrolipoamide dehydrogenase deficiency. Liver problems are likely also related to decreased energy production in cells. The degree of impairment of each complex contributes to the variability in the features of this condition.

Question: What is (are) spondyloperipheral dysplasia ?
Answer: Spondyloperipheral dysplasia is a disorder that impairs bone growth. This condition is characterized by flattened bones of the spine (platyspondyly) and unusually short fingers and toes (brachydactyly), with the exception of the first (big) toes. Other skeletal abnormalities associated with spondyloperipheral dysplasia include short stature, shortened long bones of the arms and legs, exaggerated curvature of the lower back (lordosis), and an inward- and upward-turning foot (clubfoot). Additionally, some affected individuals have nearsightedness (myopia), hearing loss, and intellectual disability.

Topic: spondyloperipheral dysplasia
Question: What are the genetic changes related to spondyloperipheral dysplasia ?
Answer: Spondyloperipheral dysplasia is one of a spectrum of skeletal disorders caused by mutations in the COL2A1 gene. This gene provides instructions for making a protein that forms type II collagen. This type of collagen is found mostly in the clear gel that fills the eyeball (the vitreous) and in cartilage. Cartilage is a tough, flexible tissue that makes up much of the skeleton during early development. Most cartilage is later converted to bone, except for the cartilage that continues to cover and protect the ends of bones and is present in the nose and external ears. Type II collagen is essential for the normal development of bones and other connective tissues that form the body's supportive framework.  Mutations in the COL2A1 gene interfere with the assembly of type II collagen molecules, reducing the amount of this type of collagen in the body. Instead of forming collagen molecules, the abnormal COL2A1 protein builds up in cartilage cells (chondrocytes). These changes disrupt the normal development of bones and other connective tissues, leading to the signs and symptoms of spondyloperipheral dysplasia.

Topic: intrauterine growth restriction, metaphyseal dysplasia, adrenal hypoplasia congenita, and genital anomalies
Question: What is (are) intrauterine growth restriction, metaphyseal dysplasia, adrenal hypoplasia congenita, and genital anomalies ?
Answer: The combination of intrauterine growth restriction, metaphyseal dysplasia, adrenal hypoplasia congenita, and genital anomalies is commonly known by the acronym IMAGe. This rare syndrome has signs and symptoms that affect many parts of the body.  Most affected individuals grow slowly before birth (intrauterine growth restriction) and are small in infancy. They have skeletal abnormalities that often become apparent in early childhood, although these abnormalities are usually mild and can be difficult to recognize on x-rays. The most common bone changes are metaphyseal dysplasia and epiphyseal dysplasia; these are malformations of the ends of long bones in the arms and legs. Some affected individuals also have an abnormal side-to-side curvature of the spine (scoliosis) or thinning of the bones (osteoporosis).  Adrenal hypoplasia congenita is the most severe feature of IMAGe syndrome. The adrenal glands are a pair of small glands on top of each kidney. They produce a variety of hormones that regulate many essential functions in the body. Underdevelopment (hypoplasia) of these glands prevents them from producing enough hormones, a condition known as adrenal insufficiency. The signs of adrenal insufficiency begin shortly after birth and include vomiting, difficulty with feeding, dehydration, extremely low blood sugar (hypoglycemia), and shock. If untreated, these complications can be life-threatening.  The genital abnormalities associated with IMAGe syndrome occur only in affected males. They include an unusually small penis (micropenis), undescended testes (cryptorchidism), and the opening of the urethra on the underside of the penis (hypospadias).  Several additional signs and symptoms have been reported in people with IMAGe syndrome. Some affected individuals have distinctive facial features, such as a prominent forehead, low-set ears, and a short nose with a flat nasal bridge. Less commonly, people with this condition have premature fusion of certain bones of the skull (craniosynostosis), a split in the soft flap of tissue that hangs from the back of the mouth (cleft or bifid uvula), a high-arched roof of the mouth (palate), and a small chin (micrognathia). Other possible features of IMAGe syndrome include high levels of calcium in the blood (hypercalcemia) or urine (hypercalcuria) and a shortage of growth hormone in childhood that results in short stature.

Question: What are the genetic changes related to intrauterine growth restriction, metaphyseal dysplasia, adrenal hypoplasia congenita, and genital anomalies ?
Answer: IMAGe syndrome is caused by mutations in the CDKN1C gene. This gene provides instructions for making a protein that helps control growth before birth. The mutations that cause IMAGe syndrome alter the structure and function of the CDKN1C protein, which inhibits normal growth starting in the early stages of development before birth. Researchers are working to determine how these genetic changes underlie the bone abnormalities, adrenal gland underdevelopment, and other signs and symptoms of this condition.  People inherit one copy of most genes from their mother and one copy from their father. For most genes, both copies are fully turned on (active) in cells. The CDKN1C gene, however, is most active when it is inherited from a person's mother. The copy of CDKN1C inherited from a person's father is active at much lower levels in most tissues. This sort of parent-specific difference in gene activation is caused by a phenomenon called genomic imprinting. When genomic imprinting reduces the activity of the copy of a gene inherited from the father, that gene is said to be paternally imprinted.

Question: Is intrauterine growth restriction, metaphyseal dysplasia, adrenal hypoplasia congenita, and genital anomalies inherited ?
Answer: The inheritance of IMAGe syndrome is complex. The condition is described as having an autosomal dominant inheritance pattern because one copy of the altered CDKN1C gene in each cell is sufficient to cause the disorder. However, because this gene is paternally imprinted, IMAGe syndrome results only when the mutation is present on the maternally inherited copy of the gene. When a mutation affects the paternally inherited copy of the CDKN1C gene, it does not cause health problems. Therefore, IMAGe syndrome is passed only from mothers to their children.

Topic: SOST-related sclerosing bone dysplasia
Question: What is (are) SOST-related sclerosing bone dysplasia ?
Answer: SOST-related sclerosing bone dysplasia is a disorder of bone development characterized by excessive bone formation (hyperostosis). As a result of hyperostosis, bones throughout the body are denser and wider than normal, particularly the bones of the skull. Affected individuals typically have an enlarged jaw with misaligned teeth. People with this condition may also have a sunken appearance of the middle of the face (midface hypoplasia), bulging eyes with shallow eye sockets (ocular proptosis), and a prominent forehead. People with this condition often experience headaches because increased thickness of the skull bones increases pressure on the brain. The excessive bone formation seen in this condition seems to occur throughout a person's life, so the skeletal features become more pronounced over time. However, the excessive bone growth may only occur in certain areas.  Abnormal bone growth can pinch (compress) the cranial nerves, which emerge from the brain and extend to various areas of the head and neck. Compression of the cranial nerves can lead to paralyzed facial muscles (facial nerve palsy), hearing loss, vision loss, and a sense of smell that is diminished (hyposmia) or completely absent (anosmia). Abnormal bone growth can cause life-threatening complications if it compresses the part of the brain that is connected to the spinal cord (the brainstem).  There are two forms of SOST-related sclerosing bone dysplasia: sclerosteosis and van Buchem disease. The two forms are distinguished by the severity of their symptoms.  Sclerosteosis is the more severe form of the disorder. People with sclerosteosis are often tall and have webbed or fused fingers (syndactyly), most often involving the second and third fingers. The syndactyly is present from birth, while the skeletal features typically appear in early childhood. People with sclerosteosis may also have absent or malformed nails.  Van Buchem disease represents the milder form of the disorder. People with van Buchem disease are typically of average height and do not have syndactyly or nail abnormalities. Affected individuals tend to have less severe cranial nerve compression, resulting in milder neurological features. In people with van Buchem disease, the skeletal features typically appear in childhood or adolescence.
