Invitae RCV001248267 SCV001421738 uncertain significance Myofibrillar myopathy 4 2019-01-26 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 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 and their clinical significance is uncertain. This variant has not been reported in the literature in individuals with LDB3-related conditions. This variant is present in population databases (rs754840310, ExAC 0.001%). This sequence change replaces threonine with serine at codon 582 of the LDB3 protein (p.Thr582Ser). The threonine residue is highly conserved and there is a small physicochemical difference between threonine and serine. The LDB3 gene has multiple clinically relevant transcripts. The p.Thr582Ser variant occurs in alternate transcript NM_007078.2, which corresponds to c.*18658C>G in NM_001080116.1, the primary transcript listed in the Methods. 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.
