HPS6

Hermansky–Pudlak syndrome 6 (HPS6), also known as ruby-eye protein homolog (Ru), is a protein that in humans is encoded by the HPS6 gene.[5]

Function

This intronless gene encodes a protein that may play a role in organelle biogenesis associated with melanosomes, platelet dense granules, and lysosomes.[6] HPS6 along with HPS3 and HPS5 form a stable protein complex named Biogenesis of Lysosome-related Organelles Complex-2 (BLOC-2).[7]

Clinical significance

Mutations in this gene are associated with Hermansky–Pudlak syndrome type 6 characterized by albinism and prolonged bleeding.[5][8]
