NCIt definition : Human PABPN1 wild-type allele is located in the vicinity of 14q11.2 and is approximately
5 kb in length. This allele, which encodes polyadenylate-binding protein 2, plays
a role in polyadenylation and poly(A) tail binding. Expansion of a GCG trinucleotide
repeat at the 5' end of the coding region from the normal 6 copies to 8-13 copies
is associated with oculopharyngeal muscular dystrophy (OPMD).;
