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]

Ambry Genetics

Aug 17, 2022

The c.632A>G (p.K211R) 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 632, causing the lysine (K) at amino acid position 211 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
