Definition of Poikiloderma atrophicans with cataract
Poikiloderma atrophicans with cataract: Better known as
the Rothmund-Thomson syndrome, this is an hereditary disease
characterized by progressive degeneration (atrophy), scarring and
abnormal pigmentation of the skin together with stunting of growth,
baldness, cataracts, depressed nasal bridge, and malformations of the
teeth, nails and bone.
Poikiloderma atrophicans with cataract (the Rothmund-Thomson
syndrome) is inherited as an autosomal
recessive trait. A child born to parents each of whom has the RTS
gene stands a 25% chance of receiving both RTS genes and having the
disease. The RTS gene has been mapped (charted) and is known to be on
chromosome 8.
The outlook (prognosis) for survival is generally fairly good. (An
alternative name for this condition is poikiloderma congenita).
