Genes affected

ALDH3B2 (HGNC:411): (aldehyde dehydrogenase 3 family member B2) This gene encodes a member of the aldehyde dehydrogenase family, a group of isozymes that may play a major role in the detoxification of aldehydes generated by alcohol metabolism and lipid peroxidation. The gene of this particular family member is over 10 kb in length. Altered methylation patterns at this locus have been observed in spermatozoa derived from patients exhibiting reduced fecundity.

The c.1034G>A (p.R345H) alteration is located in exon 10 (coding exon 8) of the ALDH3B2 gene. This alteration results from a G to A substitution at nucleotide position 1034, causing the arginine (R) at amino acid position 345 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
