Invitae	RCV000689268	SCV000816910	uncertain significance	Dysferlinopathy	2018-12-21	criteria provided, single submitter	clinical testing	This sequence change replaces arginine with histidine at codon 1720 of the DYSF protein (p.Arg1720His). The arginine residue is moderately conserved and there is a small physicochemical difference between arginine and histidine. This variant is present in population databases (rs147678255, ExAC 0.01%). This variant has not been reported in the literature in individuals with DYSF-related disease. ClinVar contains an entry for this variant (Variation ID: 282885). 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 histidine 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 and their clinical significance is uncertain. 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.
