title: Pedigree analysis of aryl hydrocarbon hydroxylase inducibility in acute leukemia of childhood.
abstract: We determined lymphocyte aryl hydrocarbon hydroxylase (AHH) inducibility for members of 13 families with one or more children with acute lymphoblastic leukemia (ALL) and 12 control families. Pedigree analysis suggested that aromatic hydrocarbon responsiveness (i.e. inducibility) is a codominant trait. Heterozygotes were found to be moderately responsive with IR values intermediate between homozygous minimally responsive and homozygous highly responsive individuals. Homozygous recessive and heterozygous genotypes accounted for 54% and 36% of ALL children respectively. The risk of ALL among minimally aromatic hydrocarbon responsive children was twice that of highly responsive children.
