Genes affected

PYROXD2 (HGNC:23517): (pyridine nucleotide-disulphide oxidoreductase domain 2) Predicted to enable oxidoreductase activity. Involved in mitochondrion organization. Located in mitochondrial matrix. [provided by Alliance of Genome Resources, Apr 2022]

PYROXD2 links:

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]
