We describe an 18-month-old male infant suffering from the ichthyosis follicularis, atrichia, and photophobia (IFAP) syndrome and further delineate the clinical phenotype. Severe retardation of growth and psychomotor development, chill-like seizures, bronchial asthma, urticaria, a proneness to skin infections and transient nail dystrophy observed in our patient are non-obligatory manifestations of this disorder. Histological examination of the atrichia revealed poorly developed, shortened hair follicles and a complete absence of sebaceous glands. The sex ratio of published cases suggests an X-linked recessive inheritance. The marked clinical variability of the IFAP syndrome might be the expression of a contiguous gene defect.

Wiskott-Aldrich syndrome (WAS) is an X-linked recessive primary immunodeficiency disorder caused by mutations in the gene encoding the WAS protein (WASP). Classic WAS is characterized by thrombocytopenia with small-sized platelets, recurrent infections, eczema and increased susceptibility to autoimmune diseases and haematologic malignancies. Here, we reported on seven unrelated Thai individuals with classic WAS. In addition to clinical and immunologic characterization, mutation analysis by PCR-sequencing the entire coding region of WASP was performed. Recurrent and novel mutations were successfully identified. A nonsense mutation, the c.55C>T (p.Q19X), has not been previously described, expanding the mutational spectrum of WASP. The patient with this newly described mutation developed cow's milk allergy manifesting as angioedema and urticaria and had cytomegalovirus infection that was successfully treated with long-term ganciclovir. This study reported long-term follow-up of seven patients with molecular confirmation of WAS and infrequent features in the patient with classic WAS carrying the novel nonsense mutation.
