Genes affected

BDH1 (HGNC:1027): (3-hydroxybutyrate dehydrogenase 1) This gene encodes a member of the short-chain dehydrogenase/reductase gene family. The encoded protein forms a homotetrameric lipid-requiring enzyme of the mitochondrial membrane and has a specific requirement for phosphatidylcholine for optimal enzymatic activity. The encoded protein catalyzes the interconversion of acetoacetate and (R)-3-hydroxybutyrate, the two major ketone bodies produced during fatty acid catabolism. Alternatively spliced transcript variants encoding the same protein have been described. [provided by RefSeq, Jul 2008]

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.641G>C (p.G214A) alteration is located in exon 8 (coding exon 6) of the BDH1 gene. This alteration results from a G to C substitution at nucleotide position 641, causing the glycine (G) at amino acid position 214 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
