We overview of a compromised Albanian lady and her 7 students. Mom is influenced by phenylketonuria and that is a material heterozygote for a couple of pathogenetic mutations, L48S and you can P281L. The brand new medical diagnosis was just produced in the brand new perspective off their youngsters, each of exactly who enjoys one big normal malformation. The initial boy, 17 years of age, features a double-chambered right ventricle, vertebral malformations and you can epilepsy.
