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 GeneticsFeb 17, 2023The c.14G>C (p.G5A) alteration is located in exon 1 (coding exon 1) of the PYROXD2 gene. This alteration results from a G to C substitution at nucleotide position 14, causing the glycine (G) at amino acid position 5 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
