Genes affected
ASPHD2 (HGNC:30437): (aspartate beta-hydroxylase domain containing 2) Predicted to enable dioxygenase activity and metal ion binding activity. Predicted to be involved in peptidyl-amino acid modification. Located in membrane. [provided by Alliance of Genome Resources, Apr 2022]
HPS4 (HGNC:15844): (HPS4 biogenesis of lysosomal organelles complex 3 subunit 2) This gene encodes a protein component of biogenesis of lysosome-related organelles complexes (BLOC). BLOC complexes are important for the formation of endosomal-lysosomal organelles such as melanosomes and platelet dense granules. Mutations in this gene result in subtype 4 of Hermansky-Pudlak syndrome, a form of albinism. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Aug 2012]
HPS4 Gene-Disease associations (from GenCC):
  • Hermansky-Pudlak syndrome 4
