Urinary Alanine Excretor in a Huntington's Chorea Family

In the course of urine-testing with Phenistix in a survey∗ of the inmates of remand homes, classifying schools and approved schools, only one positive result has been obtained from 2,300 boys and 541 girls tested so far in the London area. This was obtained with the urine of a boy who proved not to be Phenylketonuric, and further investigations were carried out in his case and with members of his family.
