Invitae | RCV001342282 | SCV001536202 | uncertain significance | Episodic kinesigenic dyskinesia | 2022-08-23 | criteria provided, single submitter | clinical testing | This sequence change replaces isoleucine, which is neutral and non-polar, with asparagine, which is neutral and polar, at codon 270 of the PRRT2 protein (p.Ile270Asn). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with paroxysmal kinesigenic dyskinesia (PMID: 32651081). ClinVar contains an entry for this variant (Variation ID: 1038906). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive. 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. |
