MSH6 and PMS2 are associated with an increased risk for breast cancer and should be considered when ordering genetic testing for individuals who have a personal and/or family history of breast cancer," lead author Maegan Roberts said in the journal statement.
Immunohistochemical testing for DNA mismatch repair (MMR) protein expression (ie, MLH1, MSH2, MSH6, and PMS2 expression) is performed on formalin-fixed, paraffin-embedded tissue.
By this analysis, SureSelect had 7 genes [SDHD, TGFBR2 (transforming growth factor, 3 receptor II [70/80 kDa]), GLA (galactosidase, a), SDHC(succinate dehydrogenase complex, subunit C, integral membrane protein, 15 kDa), COL3A1 (collagen, type III, a1), PMS2, PSCK9] for which >50% of HGMD variant locations had inadequate coverage.
12] The molecular pathogenesis of these inherited tumours is related to defects in the genes encoding the DNA mismatch repair proteins MLH1, MSH2, MSH6 and PMS2.
Hasta el presente, se informan mas de 500 mutaciones diferentes en todos los genes MMR, sin embargo, no se ha encontrado asociacion entre las mutaciones en los genes PMS1 y PMS2 y el desarrollo del CCR.
The autosomal dominant disorder is caused by a mutation in one of four DNA mismatch repair (MMR) genes: MLH1, MSH2, MSH6, or PMS2.
A variant of Lynch syndrome, the etiology of Muir-Torre Syndrome is most commonly attributed to microsatellite instability in MLH1, MSH2, MSH6, and PMS2 genes, leading to cancer of the colon, endometrium, small bowel and renal pelvis in the presence of a sebaceous tumor.
HNPCC is associated with germ-line mutations in DNA mismatch repair (MMR) genes namely MLH1, MSH2, MSH6, and PMS2 (4-7).
5) MSI is associated with mutations in the DNA mismatch repair genes hMLH1 and hMSH2, and less frequently hMSH6 and PMS2, leading to the rapid development of neoplasms through the accumulation of mutations.
Furthermore, there is evidence that mismatch repair proteins MLH1, MSH2, MSH6 and PMS2 detect and repair cisplatin-mediated DNA damage [55].
En familias que cumplen los criterios de Amsterdam I y II, se recomienda como primer paso para seleccionar las familias para el analisis de mutaciones en los genes MMR, el estudio de la IHC de las proteinas MLH1, MSH2, MSH6 y PMS2.
