Genes affected

ALDH1B1 (HGNC:407): (aldehyde dehydrogenase 1 family member B1) This protein belongs to the aldehyde dehydrogenases family of proteins. Aldehyde dehydrogenase is the second enzyme of the major oxidative pathway of alcohol metabolism. This gene does not contain introns in the coding sequence. The variation of this locus may affect the development of alcohol-related problems. [provided by RefSeq, Jul 2008]

Ambry Genetics

Nov 15, 2021

The c.218G>A (p.R73Q) alteration is located in exon 2 (coding exon 1) of the ALDH1B1 gene. This alteration results from a G to A substitution at nucleotide position 218, causing the arginine (R) at amino acid position 73 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
