Refining the role of <i>pms2</i> in Lynch syndrome: germline mutational analysis improved by comprehensive assessment of variants

Abstract

Pathogenic PMS2 mutations were detected in 69% of patients harbouring LS associated tumours with loss of PMS2 expression. In all, PMS2 mutations account for 6% of the LS cases identified. The comprehensive functional analysis shown here has been useful in the classification of PMS2 VUS and contributes to refining the role of PMS2 in LS.
