GeneDx RCV000422466 SCV000512036 benign not specified 2015-06-12 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.
Ambry Genetics RCV002450960 SCV002616851 uncertain significance Cardiovascular phenotype 2020-10-02 criteria provided, single submitter clinical testing The c.3379+4C>A intronic variant results from a C to A substitution 4 nucleotides after coding exon 29 in the ANK2 gene. This nucleotide position is not well conserved in available vertebrate species. In silico splice site analysis predicts that this alteration will not have any significant effect on splicing. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
Labcorp Genetics (formerly Invitae), Labcorp RCV002524747 SCV003020126 uncertain significance Long QT syndrome 2023-03-26 criteria provided, single submitter clinical testing 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. Variants that disrupt the consensus splice site are a relatively common cause of aberrant splicing (PMID: 17576681, 9536098). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant is not likely to affect RNA splicing. ClinVar contains an entry for this variant (Variation ID: 377476). This variant has not been reported in the literature in individuals affected with ANK2-related conditions. This variant is present in population databases (rs752152002, gnomAD 0.008%). This sequence change falls in intron 29 of the ANK2 gene. It does not directly change the encoded amino acid sequence of the ANK2 protein. It affects a nucleotide within the consensus splice site.
