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]

The c.76C>G (p.Q26E) alteration is located in exon 2 (coding exon 1) of the GPD2 gene. This alteration results from a C to G substitution at nucleotide position 76, causing the glutamine (Q) at amino acid position 26 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
