RCV004785839 | SCV005400901 | uncertain significance | Spinocerebellar ataxia type 42 | 2023-06-22 | criteria provided, single submitter | clinical testing | The missense variant c.4663C>G(p.Arg1555Gly) in CACNA1G gene has not been reported previously as a pathogenic variant nor as a benign variant, to our knowledge. The observed variant is absent in gnomAD exomes database. This variant has not been submitted to the ClinVar database. Multiple lines of computational evidence (Polyphen - probably damaging, SIFT - damaging and MutationTaster - disease causing) predict a damaging effect on protein structure and function for this variant. The reference amino acid change p.Arg1555Gly in CACNA1G is predicted as conserved by GERP++ and PhyloP across 100 vertebrates. The amino acid Arg at position 1555 is changed to a Gly changing protein sequence and it might alter its composition and physico-chemical properties. For these reasons, this variant has been classified as Uncertain Significance (VUS). |
