Description

The c.-288A>G variant located in the 5' untranslated region (5Ã¢â‚¬â„¢ UTR) of the MLH1 gene. This variant results from an A to G substitution 288 nucleotides upstream from the first translated codon. This variant was not reported in population based cohorts in the following databases: Database of Single Nucleotide Polymorphisms (dbSNP), NHLBI Exome Sequencing Project (ESP), and 1000 Genomes Project; however this position was not covered in the ESP. To date, this alteration has been detected with an allele frequency of approximately 0.01% (greater than 13000 alleles tested) in our clinical cohort (includes this individual). This nucleotide position is well conserved in available vertebrate species. Since supporting evidence is limited at this time, the clinical significance of c.-288A>G remains unclear.
