Genes affected

PTBP3 (HGNC:10253): (polypyrimidine tract binding protein 3) The protein encoded by this gene binds RNA and is a regulator of cell differentiation. The encoded protein preferentially binds to poly(G) and poly(U) sequences in vitro. Several transcript variants encoding different isoforms have been found for this gene.
