Dyskeratosis congenita

Common Name(s)

Dyskeratosis congenita

Dyskeratosis congenita is a disorder that may affect many parts of the body. Three features are especially characteristic of this disorder: (1) fingernails and toenails that grow poorly or are abnormally shaped; (2) changes in skin coloring (pigmentation), especially on the neck and chest, in a pattern often described as "lacy"; and (3) white patches inside the mouth (oral leukoplakia). People with dyskeratosis congenita also have an increased risk of developing several life-threatening conditions, including bone marrow failure, aplastic anemia, myelodysplastic syndrome, leukemia, and other cancers. The severity of dyskeratosis congenita varies widely among affected individuals. In about half of people, this condition is caused by mutations the DKC1, TERC, TERT, and TINF2 genes. Dyskeratosis congenita can have different inheritance patterns.
