distalisan

Distalisan is a rare and complex genetic disorder characterized by the absence of the distal phalanges of the fingers and toes. This condition is also known as distal symphalangism or distal symphalangism with or without hypoplasia of the metacarpals and metatarsals. It is a form of ectrodactyly, which is a group of disorders that affect the development of the fingers and toes.

The exact cause of distalisan is not fully understood, but it is believed to be due to a mutation in the gene responsible for the production of collagen, a protein that provides structure and support to the body's tissues. This mutation leads to the abnormal development of the distal phalanges, resulting in their absence.

Distalisan is typically diagnosed in infancy or early childhood through physical examination. The condition is usually asymptomatic, but in some cases, it may cause discomfort or difficulty with certain activities, such as gripping objects.

There is currently no cure for distalisan, and treatment is primarily focused on managing symptoms and providing supportive care. This may include the use of splints or braces to help maintain the alignment of the affected limbs, as well as physical therapy to improve strength and mobility. In some cases, surgery may be recommended to correct deformities or improve function.

Distalisan is a rare condition, with an estimated prevalence of less than 1 in 100,000 people. It is inherited in an autosomal dominant pattern, meaning that a person with the condition has a 50% chance of passing it on to each of their children. However, it is important to note that not all people with the gene mutation will develop the condition, and not all people with the condition will have the gene mutation.

In summary, distalisan is a rare genetic disorder characterized by the absence of the distal phalanges of the fingers and toes. It is caused by a mutation in the gene responsible for the production of collagen, and is typically diagnosed in infancy or early childhood. There is currently no cure for the condition, and treatment is focused on managing symptoms and providing supportive care.
