Invitae RCV000691051 SCV000818790 uncertain significance Bethlem myopathy 1 2019-08-30 criteria provided, single submitter clinical testing This sequence change replaces lysine with threonine at codon 610 of the COL6A1 protein (p.Lys610Thr). The lysine residue is weakly conserved and there is a moderate physicochemical difference between lysine and threonine. This variant is present in population databases (rs768906709, ExAC 0.03%). This variant has not been reported in the literature in individuals with COL6A1-related disease. ClinVar contains an entry for this variant (Variation ID: 282543). 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 threonine 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.
