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]
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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 23, 2023The c.136G>A (p.G46R) alteration is located in exon 2 (coding exon 2) of the PYROXD2 gene. This alteration results from a G to A substitution at nucleotide position 136, causing the glycine (G) at amino acid position 46 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
