Nakagawa H, Lockman JC, Frankel WL, Hampel H, Steenblock K, Burgart LJ, Thibodeau SN, de la Chapelle A. Mismatch repair gene PMS2: disease-causing germline mutations are frequent in patients whose tumors stain negative for PMS2 protein, but paralogous genes obscure mutation detection and interpretation. Cancer Res. 2004 Jul 15;64(14):4721-7. PubMed PMID: 15256438.

The authors note that, because of high population frequency, this and some other PMS2 variants obviously unrelated to disease.
