Abstract

We report on a rare case of an exon 16 mutation of the MYH9 gene in a 23-year-old woman. This gene encodes for non-muscular myosin IIA, which acts as a cytoskeletal contractile protein in diverse cell types. This disorder led to sensorineural hearing loss, macrothrombocytopenia, and proteinuria. MYH9 gene mutation can lead to diverse organ manifestation like pre-senile cataract or renal failure which are progressive in course. Due to the current lack of causal treatment, diagnostic steps, advice for follow-up examinations and symptomatic therapy approaches are presented.
