The prevalence of the mutations in the MLH1 and MSH2 genes was almost equal in our Hungarian colorectal cancer patients. One mutation in the MLH1 gene (c.143A > C; p.Q48P) was identified in three different families. Whether this mutation is the most frequent in the Hungarian population is still unidentified and warrant further investigation. The MSH2 gene provides instructions for making a protein that plays an essential role in repairing DNA. This protein helps fix errors that are made when DNA is copied (DNA replication) in preparation for cell division. or individuals with MSH2 mutations (especially males) may consider urinalysis.

Lynch syndrome is caused by mutations in the mismatch repair genes, MLH1, MSH2, MSH6, and PMS2, and the EPCAM gene. Screening for Lynch syndrome is done on the colorectal cancer tissue after surgery using immunohistochemistry .. Conventional genomic DNA sequence analysis of the mismatch repair genes MLH1, MSH2, or MSH6 revealed 28 pathogenic coding-domain mutations, 16  Germline mutations in MLH1 and MSH2 account for approximately 90% of Mutation identification after immunohistochemistry analysis positive for loss of  The MSH2 gene is associated with autosomal dominant Lynch syndrome (also called MSH2: Analysis includes the exon 1-7 inversion (Boland mutation).

To investigate further the genetic epidemiology of HNPCC and the nature and frequency of germline mutations in Of these women, 423 had a mutation in one of the four genes linked to Lynch syndrome: 15.4% had a MLH1 mutation 22.2% had an MSH2 mutation 33.1% had an MSH6 mutation 29.3% had a PMS2 mutation; In total, 107 of the 423 women (25.3%) had been diagnosed with breast cancer; six women had been diagnosed with more than one primary breast cancer.
