Women's Health and Genetics/Laboratory Corporation of America, LabCorp RCV001174793 SCV001338131 uncertain significance not specified 2020-01-31 criteria provided, single submitter clinical testing Variant summary: DMD c.5884A>C (p.Lys1962Gln) results in a conservative amino acid change located in the Central rod domain (repeat 15) of the encoded protein sequence. Five of five in-silico tools predict a benign effect of the variant on protein function. The variant was absent in 181563 control chromosomes (gnomAD). The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. c.5884A>C has been reported in the literature in at least one individual affected with late-onset Becker muscular dystrophy, but also in his two unaffected bothers who exhibited only high serum creatine kinase levels (Saad_1998). A second mutation in DMD of unknown significance, reported as c.5911T>C, was also detected in the affected patient, and the contributions of each variant to the phenotype could not be determined from this study. To our knowledge,neither of these variants has been reported in other dystropinopathy patients alone or in combination and no experimental evidence demonstrating an impact on protein function has been reported. Thus, these data do not provide unequivocal conclusions about association of the variant with Dystrophinopathies. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014. Based on the evidence outlined above, the variant was classified as uncertain significance.
