MSH3 forms a heterodimer with MSH2 to form the MSH3:MSH2 complex, part of the post-replicative DNA mismatch repair system. The MSH3 414TER variant represented here was identified in an endometrial carcinoma cell line (Risinger et al., 1996). The mutation resulted in a truncated product and consisted of a single nucleotide deletion, loss of an A/T basepair at position 1148. This change generated a premature nonsense codon and results in a protein 723 amino acids shorter than the wildtype gene product.
