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]

Ambry Genetics

Oct 27, 2023

The c.608C>T (p.P203L) alteration is located in exon 8 (coding exon 6) of the BDH1 gene. This alteration results from a C to T substitution at nucleotide position 608, causing the proline (P) at amino acid position 203 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
