Frequency distribution of the Los Angeles and Duarte galactose-1-phosphate uridyltransferase variant alleles in the Irish population.
Anonymous population screening was carried out to detect the N314D, Los Angeles (D1), and Duarte (D2) alleles of the galactose-1-phosphate uridyltransferase gene in Ireland using 743 blood samples, covering the Traveller (n = 243) and non-Traveller (n = 500) population groups. The frequency of the N314D substitution was found to be 0.099 overall. D1 allele frequencies were found to be 0.031 and 0.023 in the Traveller and non-Traveller groups, respectively, while D2 allele frequencies were 0.058 and 0.076, respectively. No significant differences in allele frequency were detected between the Traveller and non-Traveller groups, or between the Irish population groups and the literature values for Northern and Western Europe.
