title: Geographical variations in inborn errors of metabolism in Japan.
abstract: Using materials from a nationwide screening project on inborn errors of metabolism in Japan, the incidence of histidinemia, phenylketonuria, galactosemia and homocystinuria were found to be 140, 16, 14 and 7 in 1 million live births, respectively. Geographical variations were observed, especially in histidinemia, which are most likely due to chance.
