if pku isn't controlled through changes in weight loss plan, it is able to motive intense highbrow and developmental incapacity.

what causes phenylketonuria?
pku is an inherited ailment. this indicates it's far passed down thru the genes of the mother and father. it is resulting from mutations in the gene that helps make an enzyme referred to as phenylalanine hydroxylase. this enzyme enables wreck down phenylalanine. whilst this gene doesn’t work proper, the body can’t damage down phenylalanine. it begins to accumulate and reasons damage to nerve cells within the brain.
