  • Mothers of children with phenylketonuria have a significantly lower miscarriage rate than a matched control population in Ireland and west Scotland. This protective effect of the gene against some factor causing foetal death would seem to constitute a heterozygote advantage which might account for the previously observed polymorphism for phenylketonuria. It is suggested that the decrease in foetal mortality is mediated by the higher concentration of phenylalanine in the heterozygous mother's… CONTINUE READING
