متن کاملHomocystinuria: Heterozygote Detection
cytes as a readily available source of this enzyme, its activity has been compared in 48 control subjects, seven homozygotes affected with homocystinuria, and 17 obligate heterozygotes. PHA-induced enzyme levels were highest in controls (mean ±SEM, 666.9±170.2 pmol cystathionine formed/mg protein per 4 h), intermediate in heterozygotes (114.4±27.3), and absent to severely deficient in homozygot...
