Invitae RCV001217838 SCV001389694 uncertain significance Duchenne muscular dystrophy 2019-07-18 criteria provided, single submitter clinical testing This sequence change replaces threonine with proline at codon 148 of the DMD protein (p.Thr148Pro). The threonine residue is highly conserved and there is a small physicochemical difference between threonine and proline. This variant is not present in population databases (ExAC no frequency). This variant has been observed in an individual affected with Duchenne muscular dystrophy (PMID: 31081998). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive, but 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.
