TY - JOUR T1 - Hair Amino Acids JF - Archives of Disease in Childhood JO - Arch Dis Child SP - 678 LP - 681 DO - 10.1136/adc.45.243.678 VL - 45 IS - 243 AU - Marc Van Sande Y1 - 1970/10/01 UR - http://adc.bmj.com/content/45/243/678.abstract N2 - Hair amino acids have been studied in 10 controls and in 25 patients suffering from metabolic inborn errors. Abnormalities of hair amino acid pattern were found in several cases. In phenylketonuria (7 cases), the hair phenylalanine level was significantly higher than that of the normal subjects. Glutamic acid was decreased. In homocystinuria (5 cases), the phenylalanine level was increased. The results suggest that a detailed examination of the hair proteins could give further information.
