Ichthyosis follicularis with alopecia and photophobia syndrome
|Classification and external resources|
IFAP syndrome is an extremely rare genetic syndrome. It is also known as Ichthyosis follicularis, alopecia, and photophobia syndrome or simply ichthyosis follicularis.:564 It is extremely rare: there were only 10 known cases (all male) in 1998.
The main symptoms are given by its name: dry, scaly skin (ichthyosis), absence of hair (atrichia) and excessive sensitivity to light (photophobia). Additional features include short stature, mental retardation, seizures and a tendency for respiratory infections.
Most cases are X-linked recessive but there may be as many as three types. As well as a classical X-linked form, there is another type where females are partially affected and another where females have full IFAP symptoms. The gene or genes causing this disease are not known.
