The article discusses phenylketonuria. It is a hereditary disease which was first described by a Norwegian biochemist in 1934. He showed that a group of mentally deficient patients could be distinguished by the presence of phenylpyruvic acid in the urine. Since then, several hundred such patients have been discovered in different parts of the world and it is believed that such a case occurs once in every 40,000 births in the United States. Clinically, these patients appear to be ordinary imbeciles; however, certain features about them permit an experienced physician to suspect the diagnosis even before the urine has been tested. In the first place, they tend to show more normal physical development than among non-phenylketonurics of a comparable mental level. |
