Invitae | RCV000652517 | SCV000774387 | likely pathogenic | Catecholaminergic polymorphic ventricular tachycardia 4; Long QT syndrome 14 | 2020-06-04 | criteria provided, single submitter | clinical testing | In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. Algorithms developed to predict the effect of missense changes on protein structure and function do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C65"). This variant has been observed to be de novo in an individual affected with a CALM1-related disease (Invitae). This variant is not present in population databases (ExAC no frequency). This sequence change replaces glycine with glutamic acid at codon 133 of the CALM1 protein (p.Gly133Glu). The glycine residue is highly conserved and there is a moderate physicochemical difference between glycine and glutamic acid. |
