Variant summary: VMA21 c.-382C>T is located in the untranscribed region upstream of the VMA21 gene region. The variant was absent in 20650 control chromosomes (gnomAD). The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. To our knowledge, no occurrence of c.-382C>T in individuals affected with X-Linked Myopathy With Excessive Autophagy and no experimental evidence demonstrating its impact on protein function have been reported. No submitters have cited clinical-significance assessments for this variant to ClinVar. Based on the evidence outlined above, the variant was classified as uncertain significance. -
