IFAP syndrome is an extremely rare genetic syndrome. It is also known as Ichthyosis follicularis, alopecia, and photophobia syndrome or simply ichthyosis follicularis.[2]: 564 It is extremely rare: there were only 40 known cases (all male) until 2011.[3]
Symptoms and signs
[edit]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.[4]
Genetics
[edit]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.[4]
Diagnosis
[edit]Diagnosis is based on appearance and family history. KID syndrome or keratosis follicularis spinulosa decalvans have some similar symptoms and must be eliminated.[5]
