| Invitae | RCV000472470 | SCV000543266 | uncertain significance | Dilated cardiomyopathy with woolly hair and keratoderma; Arrhythmogenic right ventricular cardiomyopathy, type 8 | 2016-11-12 | criteria provided, single submitter | clinical testing | This sequence change replaces threonine with serine at codon 1217 of the DSP protein (p.Thr1217Ser). The threonine residue is moderately conserved and there is a small physicochemical difference between threonine and serine. This variant is present in population databases (rs770484693, ExAC 0.002%) but has not been reported in the literature in individuals with a DSP-related disease. 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 serine amino acid residue is found in multiple mammalian species, suggesting that this missense change does not adversely affect protein function. These predictions have not been confirmed by published functional studies. In summary, this variant is a rare missense change that is not predicted to affect protein function. There is no indication that it causes disease, but the available evidence is currently insufficient to prove that conclusively. Therefore, it has been classified as a Variant of Uncertain Significance. |
