Genes affected

HPS1 (HGNC:5163): (HPS1 biogenesis of lysosomal organelles complex 3 subunit 1) This gene encodes a protein that may play a role in organelle biogenesis associated with melanosomes, platelet dense granules, and lysosomes. The encoded protein is a component of three different protein complexes termed biogenesis of lysosome-related organelles complex (BLOC)-3, BLOC4, and BLOC5. Mutations in this gene are associated with Hermansky-Pudlak syndrome type 1. Alternative splicing results in multiple transcript variants. A pseudogene related to this gene is located on chromosome 22. [provided by RefSeq, Aug 2015]

The Arg158Cys variant in HPS1 has not been reported in individuals with pulmonar y disease and data from large population studies is insufficient to assess the f requency of this variant. Computational prediction tools and conservation analys es suggest that this variant may not impact the protein, though this information is not predictive enough to rule out pathogenicity. In summary, additional info rmation is needed to fully assess the clinical significance of the Arg158Cys var iant. -
