This duplication of four nucleotides in MSH6 is denoted c.3753_3756dupATTA at the cDNA level and p.Val1253IlefsX23 (V1253IfsX23) at the protein level. The normal sequence, with the bases that are duplicated in braces, is ATTC[ATTA]GTAG. The duplication causes a frameshift, which changes a Valine to an Isoleucine at codon 1253, and creates a premature stop codon at position 23 of the new reading frame. Although this variant has not, to our knowledge, been reported in the literature, it is predicted to cause loss of normal protein function through either protein truncation or nonsense-mediated mRNA decay. We consider this variant to be pathogenic.
