Genes affected
HIBADH (HGNC:4907): (3-hydroxyisobutyrate dehydrogenase) This gene encodes a mitochondrial 3-hydroxyisobutyrate dehydrogenase enzyme. The encoded protein plays a critical role in the catabolism of L-valine by catalyzing the oxidation of 3-hydroxyisobutyrate to methylmalonate semialdehyde. [provided by RefSeq, Nov 2011]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 18, 2022The c.710C>A (p.P237Q) alteration is located in exon 7 (coding exon 7) of the HIBADH gene. This alteration results from a C to A substitution at nucleotide position 710, causing the proline (P) at amino acid position 237 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
