RCV000600646 | SCV000715945 | likely benign | not specified | 2017-02-14 | criteria provided, single submitter | clinical testing | This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease. |

RCV000600646 | SCV001737848 | uncertain significance | not specified | 2021-05-24 | criteria provided, single submitter | clinical testing | Variant summary: SNTA1 c.702-7C>G alters a nucleotide located close to a canonical splice site and therefore could affect mRNA splicing, leading to a significantly altered protein sequence. Several computational tools predict an impact on normal splicing: Four predict the variant slightly weakens a 3' acceptor site. However, these predictions have yet to be confirmed by functional studies. The variant allele was found at a frequency of 8.8e-06 in 226540 control chromosomes. The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. To our knowledge, no occurrence of c.702-7C>G in individuals affected with Long QT Syndrome and no experimental evidence demonstrating its impact on protein function have been reported. Two clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation. One laboratory classified the variant as likely benign, and one laboratory classified the variant as uncertain significance. Based on the evidence outlined above, the variant was classified as uncertain significance. |
