Genes affected
GPD2 (HGNC:4456): (glycerol-3-phosphate dehydrogenase 2) The protein encoded by this gene localizes to the inner mitochondrial membrane and catalyzes the conversion of glycerol-3-phosphate to dihydroxyacetone phosphate, using FAD as a cofactor. Along with GDP1, the encoded protein constitutes the glycerol phosphate shuttle, which reoxidizes NADH formed during glycolysis. Two transcript variants encoding the same protein have been found for this gene.[provided by RefSeq, Jan 2010]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 08, 2023The c.529A>G (p.I177V) alteration is located in exon 6 (coding exon 5) of the GPD2 gene. This alteration results from a A to G substitution at nucleotide position 529, causing the isoleucine (I) at amino acid position 177 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
