Histo-blood group Lewis genotyping from human hairs and blood.
The expression of histo-blood group Lewis antigens is determined by the Lewis-type alpha 1-->3/4fucosyltransferase (Le enzyme) encoded by Fuc-TIII gene (Le gene). The genotyping of Le genes by the PCR-RFLP methods established recently and partly modified in this study was found to be useful not only for determining the genuine Lewis blood types of samples such as human hairs and blood stains but also for distinguishing non-genuine Lewis-negative phenotypes frequently observed in pregnant women from genuine ones. The availability of the present PCR-RFLP methods for the paternity tests was also discussed.
