Myriad Genetics, Inc. RCV002309767 SCV002603646 likely pathogenic Miyoshi muscular dystrophy 1; Autosomal recessive limb-girdle muscular dystrophy type 2B; Distal myopathy with anterior tibial onset 2022-02-17 criteria provided, single submitter clinical testing NM_003494.3(DYSF):c.4806C>A(Y1602*) is expected to be pathogenic in the context of dysferlinopathy. This variant is predicted to lead to an abnormal or absent protein product due to the creation of a premature termination codon in DYSF, a gene where loss-of-function variants are known to be pathogenic. Please note: this variant was assessed in the context of healthy population screening.
Labcorp Genetics (formerly Invitae), Labcorp RCV003738180 SCV004464465 pathogenic Qualitative or quantitative defects of dysferlin 2023-05-19 criteria provided, single submitter clinical testing Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. For these reasons, this variant has been classified as Pathogenic. ClinVar contains an entry for this variant (Variation ID: 1724499). This variant has not been reported in the literature in individuals affected with DYSF-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change creates a premature translational stop signal (p.Tyr1602*) in the DYSF gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in DYSF are known to be pathogenic (PMID: 17698709, 20301480).
