title: DNA haplotype analysis at the phenylalanine hydroxylase locus in the Turkish population.
abstract: Thirty-nine Turkish phenylketonuria (PKU) families were investigated for their DNA haplotypes at the phenylalanine hydroxylase (PAH) locus. There was a threefold higher incidence of consanguinity in the population studied compared with the general Turkish population. The PAH DNA haplotype 6 was found to be almost exclusively associated not only with the mutant PAH genes but also with the classic phenotype in 39% of the Turkish patients. This haplotype was of not importance in northern European populations. The two DNA haplotypes (1 and 4) that were almost equally frequent among the normal and the mutant PAH genes in northern European populations show virtually the same distribution in Turkish individuals. In all populations studied, these haplotypes are associated with different phenotypes.
