Genes affected
MYOF (HGNC:3656): (myoferlin) Mutations in dysferlin, a protein associated with the plasma membrane, can cause muscle weakness that affects both proximal and distal muscles. The protein encoded by this gene is a type II membrane protein that is structurally similar to dysferlin. It is a member of the ferlin family and associates with both plasma and nuclear membranes. The protein contains C2 domains that play a role in calcium-mediated membrane fusion events, suggesting that it may be involved in membrane regeneration and repair. Two transcript variants encoding different isoforms have been found for this gene. Other possible variants have been detected, but their full-length nature has not been determined.

| Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Feb 13, 2024 | The c.5785G>A (p.A1929T) alteration is located in exon 51 (coding exon 51) of the MYOF gene. This alteration results from a G to A substitution at nucleotide position 5785, causing the alanine (A) at amino acid position 1929 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
