<p>This subsection of the ‘Sequence’ section provides information on polymorphic variants. If the variant is associated with a disease state, the description of the latter can be found in the <a href="http://www.uniprot.org/manual/involvement_in_disease">'Involvement in disease'</a> subsection.<p><a href='/help/polymorphism' target='_top'>More...</a></p>Polymorphismi

In most individuals a nonsense mutation transforms the Arg-140 into a premature stop codon. Out of 1217 individuals, 1166 had a stop codon in both alleles, 50 were heterozygous and only one (in the Philippines) had Arg-140 in both alleles. GPR33 has undergone independent pseudogenization in human, chimpanzee, orangutan, siamang and rat. This selective inactivation may be due to its interaction with a putative pathogen that could use GPR33 as a receptor for cell invasion.1 Publication
