A genetic test which can be used to diagnose adult-type hypolactasia in children

SMALL INTESTINE A genetic test which can be used to diagnose adult-type hypolactasia in children

Background/Aims: Adult-type hypolactasia (primary lactose malabsorption) affects most of world’s human population and limits the use of fresh milk due to lactose intolerance. The diagnosis of adult-type hypolactasia has been difficult to establish because of unsatisfactory diagnostic methods. C/T-13910 single nucleotide polymorphism residing 13910 base pairs from the 59 end of the lactase gene ...

Evaluation of a Genetic Test for Diagnose of Primary Hypolactasia in Northeast of Iran (Khorasan)

Objective(s) Primary or adult type hypolactasia, the most common enzyme deficiency in the world, is due to reduced lactase activity in the intestinal cell after weaning. Lactase non-persistence is inherited as an autosomal recessive trait. A DNA variant, single nucleotide polymorphism C/T−13910 which is located on 13910 base pairs (bp) upstream of the lactase gene (LCT) at chromosome 2 has been...

Genetic Aspects of Adult-Type Hypolactasia

Background and objective: Lactose is a disaccharide sugar and is found in mammals milk and derivatives. Lactose intolerance is the inability to metabolize lactose, because of a lack of the required enzyme lactase in the digestive system. Genetically the physiological hypolactasia (primary LM) is associated with the LCT-13910 C/T and LCT-22018 G/A polymorphisms. The aim of this study focused on ...
