Genes affected

BDH2 (HGNC:32389): (3-hydroxybutyrate dehydrogenase 2) Enables 3-hydroxybutyrate dehydrogenase activity and NAD binding activity. Involved in epithelial cell differentiation and fatty acid beta-oxidation. Located in cytosol. [provided by Alliance of Genome Resources, Apr 2022]

BDH2 (HGNC:):

BDH2 links:

SLC9B2 (HGNC:25143): (solute carrier family 9 member B2) Sodium hydrogen antiporters, such as NHEDC2, convert the proton motive force established by the respiratory chain or the F1F0 mitochondrial ATPase into sodium gradients that drive other energy-requiring processes, transduce environmental signals into cell responses, or function in drug efflux (Xiang et al., 2007 [PubMed 18000046]).[supplied by OMIM, Mar 2008]

Ambry Genetics

Oct 14, 2021

The c.460G>A (p.V154M) alteration is located in exon 7 (coding exon 6) of the BDH2 gene. This alteration results from a G to A substitution at nucleotide position 460, causing the valine (V) at amino acid position 154 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
