Genes affected

DYSF (HGNC:3097): (dysferlin) The protein encoded by this gene belongs to the ferlin family and is a skeletal muscle protein found associated with the sarcolemma. It is involved in muscle contraction and contains C2 domains that play a role in calcium-mediated membrane fusion events, suggesting that it may be involved in membrane regeneration and repair. In addition, the protein encoded by this gene binds caveolin-3, a skeletal muscle membrane protein which is important in the formation of caveolae. Specific mutations in this gene have been shown to cause autosomal recessive limb girdle muscular dystrophy type 2B (LGMD2B) as well as Miyoshi myopathy. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Aug 2008]

Variant summary: DYSF c.4096G>A (p.Val1366Met) results in a conservative amino acid change in the encoded protein sequence. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change. The variant allele was found at a frequency of 4e-06 in 251378 control chromosomes (gnomAD). The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. c.4096G>A has been observed in at least one individual affected with Limb-Girdle Muscular Dystrophy, however this patient carried two co-occurring likely pathogenic variants in cis and trans, which could explain the phenotype (Yu_2017). This report does not provide unequivocal conclusions about association of the variant with Limb-Girdle Muscular Dystrophy, Autosomal Recessive. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. The following publication has been ascertained in the context of this evaluation (PMID: 28403181). ClinVar contains an entry for this variant (Variation ID: 555389). Based on the evidence outlined above, the variant was classified as uncertain significance.
