Entrez Gene Summary for A4GALT Gene

  • The protein encoded by this gene catalyzes the transfer of galactose to lactosylceramide to form globotriaosylceramide, which has been identified as the P(k) antigen of the P blood group system. The encoded protein, which is a type II membrane protein found in the Golgi, is also required for the synthesis of the bacterial verotoxins receptor. [provided by RefSeq, Jul 2008]

Variants for A4GALT Gene

Polymorphic Variants from UniProtKB/Swiss-Prot for A4GALT Gene

Q9NPC4-A4GAT_HUMAN
Genetic variation in A4GALT is responsible for the P system blood group phenotypes [MIM:111400]. Different combinations or absence of the P blood group system antigens define 5 different phenotypes: P1, P2, P1(k), P2(k), and p. Genetic variation in A4GALT determines the p phenotype, which is rare and does not express any antigens. It is also known as null phenotype; p individuals have antibodies against P, P1 and Pk antigens in their sera. These antibodies are clinically important because they can cause severe transfusion reactions and miscarriage
