Genes affected
HPS6 (HGNC:18817): (HPS6 biogenesis of lysosomal organelles complex 2 subunit 3) This intronless gene encodes a protein that may play a role in organelle biogenesis associated with melanosomes, platelet dense granules, and lysosomes. This protein interacts with Hermansky-Pudlak syndrome 5 protein. Mutations in this gene are associated with Hermansky-Pudlak syndrome type 6. [provided by RefSeq, Jul 2008]

Submissions by phenotype

not provided Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpJul 29, 2022This sequence change replaces glycine, which is neutral and non-polar, with arginine, which is basic and polar, at codon 5 of the HPS6 protein (p.Gly5Arg). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with HPS6-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C15"). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
