Variant summary: VMA21 c.-290G>A is located in the untranscribed region upstream of the VMA21 gene region. The variant was detected at a frequency of 4.5e-05 in 110157 control chromosomes, including 3 hemizygotes. 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.-290G>A 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. -
