GeneDx RCV000484286 SCV000568726 uncertain significance not provided 2016-12-07 criteria provided, single submitter clinical testing This in-frame deletion of three nucleotides in MSH6 is denoted c.3485_3487delCTG at the cDNA level and p.Ala1162del (A1162del) at the protein level. The normal sequence, with the bases that are deleted in brackets, is CCTG[delCTG]AAGT. This deletion occurs in a region that is conserved across species and is located in domain V of the MutS domain (Terui 2013). In silico analyses predict that this variant is probably damaging to protein structure and function. This variant has not, to our knowledge, been published in the literature as pathogenic or benign. Since in-frame deletions may or may not inhibit proper protein functioning, the clinical significance of this finding remains unclear at this time and we consider MSH6 Ala1162del to be a variant of uncertain significance.
Invitae RCV000542403 SCV000624874 uncertain significance Hereditary nonpolyposis colorectal neoplasms 2018-10-30 criteria provided, single submitter clinical testing This variant, c.3485_3487delCTG, results in the deletion of 1 amino acid of the MSH6 protein (p.Ala1162del), but otherwise preserves the integrity of the reading frame. This variant is not present in population databases (ExAC no frequency). This variant has been observed in individuals with suspected Lynch syndrome (PMID: 22658618, 28514183). ClinVar contains an entry for this variant (Variation ID: 140774). Experimental studies and prediction algorithms are not available for this variant, and the functional significance of the deleted amino acid is currently unknown. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance.
