extramammary Paget disease mismatch repair mutations
摘要：

Extramammary Paget disease (EMPD) is a rare cutaneous malignant neoplasm. The familial occurrence of EMPD and the high risk of concomitant secondary tumors in EMPD patients have gained much attention. These findings highlight the importance of genetic alterations in the tumorigenesis of this skin cancer. Genetic tests and functional analysis of mismatch repair (MMR) genes were performed in EMPD. The results showed that 8 of 20 cases with germline MMR genes mutations and 5 of them exhibited microsatellite instability (MSI). Immunohistochemical staining showed that the tumor tissues from 20 patients had the normal expression of MLH1 but 5 cases had the reduced expression of MSH2. There is a nearly significant correlation between MSI and germline mutations. In 172 cases, rates of germline and somatic mutations were 34.3% and 13.4%, respectively. The mutations of MLH1 V384D (15.7%), R217C (4.1%), and I219V (5.2%) were common in this cancer. In addition, the yeast 2-hybrid and immunoprecipitation assays exhibited reduced interaction between MLH1 and PMS2 in MLH1 V384D and R217C but not I219V. Moreover, MLH1 V384D and R217C had impaired MMR activity compared with the wild-type and I219V mutation by an in vitro MMR assay. The germline mutations in MMR genes are involved in the patho-genesis of EMPD and partially explain the genetic abnormalities for this disease.
