Genes affected

ETFB (HGNC:3482): (electron transfer flavoprotein subunit beta) This gene encodes electron-transfer-flavoprotein, beta polypeptide, which shuttles electrons between primary flavoprotein dehydrogenases involved in mitochondrial fatty acid and amino acid catabolism and the membrane-bound electron transfer flavoprotein ubiquinone oxidoreductase. The gene deficiencies have been implicated in type II glutaricaciduria. Alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Jul 2008]

The c.736G>A (p.V246M) alteration is located in exon 6 (coding exon 6) of the ETFB gene. This alteration results from a G to A substitution at nucleotide position 736, causing the valine (V) at amino acid position 246 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
