Abstract
The codon 408 mutation (CGG----TGG, Arg----Trp) in exon 12 of the phenylalanine hydroxylase (PAH) gene occurs on haplotype 1 in French-Canadians; elsewhere this mutation (R408W) occurs on haplotype 2. A CpG dinucleotide is involved. The finding is compatible with a recurrent mutation, gene conversion, or a single recombination between haplotypes 2 and 1. A tabulation of 20 known mutations at the PAH locus reveals three instances of putative recurrent mutation.Entities:
