When comparing the frequencies of the 3′-UTRs of the BRCA1 G>T heterozygosity in this study group with those of other studies, it was found that the GT heterozygosity was generally comparable with Italy (TSI) at 50%; Chinese in Colorado (CHD) at 56%; Gujarati Indians in Houston, Texas (GIH) at 52%; European ancestry in Utah at %45; and 50% in a Saudi Arabian population [14].
