Genotype-phenotype correlations in individuals with a founder mutation in the MLH1 gene and hereditary non-polyposis colorectal cancer.


OBJECTIVE A unique mutation of the MLH1 gene was recently reported in six families living in a small area of Northern Italy. The mutation consists in the insertion of a T base between nucleotides 2269 and 2270 (2269-2270insT), causing the synthesis of an unstable polypeptide. The mutation was not reported by other investigators or outside this small… (More)
