Chondrodysplasia Punctata 1, X-Linked Recessive
Chondrodysplasia punctata 1, X-linked recessive (CDPX1) is a genetic disorder present from birth that affects bone and cartilage development. On x-ray, infants with CDPX1 have characteristic spots at the ends of their bones. These spots are called chondrodysplasia punctata or stippled epiphyses and typically disappear between ages 2 and 3. Additional common features of CDPX1 are shortened fingers and a flattened nose. Some people with this condition have breathing abnormalities, hearing loss, abnormalities of the spinal bones in the neck, and intellectual delays.
CDPX1 is caused by mutations in the ARSE gene, which is located on the X chromosome. This condition is inherited in an X-linked recessive manner and occurs almost exclusively in males. Most affected individuals have a normal lifespan, although some individuals experience complications that can be life-threatening. Although there is no specific treatment or cure for CDPX1, there are ways to manage symptoms. A team of doctors or specialists is often needed to figure out the treatment options for each person.
