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 GeneticsOct 11, 2024The c.265G>A (p.V89I) alteration is located in exon 3 (coding exon 2) of the GPD2 gene. This alteration results from a G to A substitution at nucleotide position 265, causing the valine (V) at amino acid position 89 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
