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.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 07, 2023The c.841C>G (p.L281V) alteration is located in exon 8 (coding exon 6) of the ALDH3B2 gene. This alteration results from a C to G substitution at nucleotide position 841, causing the leucine (L) at amino acid position 281 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
