Hermansky-Pudlak syndrome is common in an isolated mountain village in the Swiss Alps in the canton Valais. It has also been reported to be more common in persons of Dutch descent. Turkish and Pakistani kindreds have been reported. Cases have been reported in Japan as well. Hermansky-Pudlak syndrome has now been reported in African Americans, specifically in 2 brothers who carried compound heterozygous mutations in HPS-1: 1 mutation previously noted, p.M325WfsX6 (c.972delC), and a novel silent mutation that resulted in a splice defect at p.E169E (c.507G > A). [19] Hermansky-Pudlak syndrome has also been reported in a patient of Indian descent. [20]
