Labcorp Genetics (formerly Invitae), Labcorp RCV001854168 SCV002135927 uncertain significance Desmin-related myofibrillar myopathy 2022-06-15 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. Studies have shown that disruption of this splice site results in skipping of exon 3, but is expected to preserve the integrity of the reading-frame (PMID: 11073539). ClinVar contains an entry for this variant (Variation ID: 66416). This variant is also known as IVS2-2A>G. Disruption of this splice site has been observed in individuals with clinical features of autosomal dominant DES-related conditions (PMID: 14724127, 17626518, 19716701). This variant is not present in population databases (gnomAD no frequency). This sequence change affects an acceptor splice site in intron 2 of the DES gene. RNA analysis indicates that disruption of this splice site induces altered splicing and likely results in a shortened protein product.
