A Novel Mutation Leading to Wiskott-Aldrich Syndrome in an Ethiopian Boy: a Case Report and a Review of Literature.

Wiskott-Aldrich syndrome is an X-linked recessive primary immune-deficiency disorder very rarely reported from black African children. A 12-year old boy with recurrent sinopulmonary and diarrheal infections, eczema, thrombocytopenia, and low platelet volume was found by whole genome sequencing to harbor a predicted pathogenic c.1205dupC (p.Pro403Alafs*92) variant of a mutation in the WAS gene - confirming the diagnosis. This case report summarizes his presentation and management and provides a useful summary of the diagnosis and the responsible novel genetic mutation.
