Description

Variant summary: MUSK c.549A>G alters a conserved nucleotide resulting in a synonymous change. Consensus agreement among computation tools predict no significant impact on normal splicing. However, these predictions have yet to be confirmed by functional studies. The variant allele was found at a frequency of 9.7e-05 in 248688 control chromosomes (gnomAD). To our knowledge, no occurrence of c.549A>G in individuals affected with MUSK-Related Disorders and no experimental evidence demonstrating its impact on protein function have been reported. Two submitters have cited clinical-significance assessments for this variant to ClinVar after 2014. One submitter classified the variant as likely benign, and one submitter classified the variant as uncertain significance. Based on the evidence outlined above, the variant was classified as likely benign.
