About Distal trisomy 22q

What is Distal trisomy 22q?

Distal trisomy 22q is a rare chromosomal disorder caused by an extra copy of genetic material on the long arm (q) of chromosome 22. It is characterized by a wide range of physical and developmental abnormalities, including heart defects, facial abnormalities, and intellectual disability.

What are the symptoms of Distal trisomy 22q?

The symptoms of Distal trisomy 22q vary depending on the size and location of the extra chromosome material. Common symptoms include developmental delays, intellectual disability, heart defects, cleft lip or palate, kidney abnormalities, hearing loss, vision problems, and skeletal abnormalities.

What are the causes of Distal trisomy 22q?

It is caused by a random error in cell division called nondisjunction. This error can occur during the formation of either the egg or the sperm cell, resulting in an embryo with an extra copy of the genetic material on chromosome 22.
