Abstract

We searched for a difference in allele distribution between males and females of a single nucleotide polymorphism located in the human beta T-cell receptor, in 500 subjects (200 males and 300 females). Genotype analysis gave the following results: among the males, 114 (57%) were heterozygous for the T/C polymorphism, 52 (26%) were homozygous (T/T), and 34 (17%) were homozygous (C/C). Among the females, 142 (47.3%) were heterozygous, 73 (24.3%) were homozygous (T/T), and 85 (28.3%) were homozygous (C/C). The allele frequency was significantly different between sexes (χ2 = 8.799, P = 0.012).
