Invitae RCV000804064 SCV000943958 uncertain significance Congenital myasthenic syndrome 8 2021-04-01 criteria provided, single submitter clinical testing In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site, but this prediction has not been confirmed by published transcriptional studies. This variant has not been reported in the literature in individuals with AGRN-related disease. The frequency data for this variant in the population databases is considered unreliable, as metrics indicate insufficient coverage at this position in the ExAC database. This sequence change affects codon 1820 of the AGRN mRNA. It is a 'silent' change, meaning that it does not change the encoded amino acid sequence of the AGRN protein.
