[Heredity of poor digestion of lactose].
The published reports on the possibility that the adult type of lactose maldigestion is a hereditary condition are reviewed. The ethnic variability in the frequency of this trait, together with twin and family studies, suggest that this is indeed the case. Family studies, including the one performed in Mexico, indicates that the adult type of lactose maldigestion is inherited in an autosomic recessive manner.
