Variant summary: VMA21 c.-486C>T is located in the untranscribed region upstream of the VMA21 gene region. The variant allele was found at a frequency of 9e-05 in 110733 control chromosomes (gnomAD v3.1.2). To our knowledge, no occurrence of c.-486C>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 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. -
