Abstract

Objective: To determine the prevalence of adult-type hypolactasia in the Tajik population living in the south of Uzbekistan by genotyping of allelic variants C/T-13910 and identifying their tolerance to milk. Methods: 100 ethnic Tajik adults were examined for C/T-13910 single nucleotide polymorphisms using polymerase chain reaction/restriction fragment length polymorphism. Milk tolerance was analyzed by a questionnaire developed to assess dyspepsia after milk and dairy consumption. Results: A genetic marker of hypolactasia - C/C-13910 genotype was detected in 83% of the adult Tajik population. However, despite the high prevalence of lactose intolerance in the Tajik population, the majority consume between 100-200 ml of milk per day. Conclusion: The Tajik population is characterized by a high prevalence of hypolactasia. Milk consumption is not affected by the determined genotypes since people of Tajik ethnicity consume milk in small quantities.
