RCV002947975 | SCV003269286 | uncertain significance | Myoclonic dystonia 26 | 2022-04-10 | criteria provided, single submitter | clinical testing | Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The cysteine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. 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. This variant has not been reported in the literature in individuals affected with KCTD17-related conditions. The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This sequence change replaces arginine, which is basic and polar, with cysteine, which is neutral and slightly polar, at codon 271 of the KCTD17 protein (p.Arg271Cys). |
Ambry Genetics | RCV002947976 | SCV003604671 | uncertain significance | Inborn genetic diseases | 2022-01-07 | criteria provided, single submitter | clinical testing | The c.739C>T (p.R247C) alteration is located in exon 7 (coding exon 7) of the KCTD17 gene. This alteration results from a C to T substitution at nucleotide position 739, causing the arginine (R) at amino acid position 247 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. |
