Submissions by phenotype
Hereditary cancer-predisposing syndrome Uncertain:1
The c.-103G>T variant is located in the 5' untranslated region (5’ UTR) of the MSH2 gene. This variant results from a G to T substitution 103 bases upstream from the first translated codon. This nucleotide position is well conserved in available vertebrate species. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
