The mouse and rat Aldh3b3 genes appear to represent new orthologous ALDH family members; the genes reside in syntenic chromosomal regions and share a high degree (83.4 per cent) of sequence identity with one another. The two proteins are more divergent than the rodent ALDH3B2 orthologues, which share 89.9 per cent sequence identity.
