Genes affected

SYNC (HGNC:28897): (syncoilin, intermediate filament protein) This gene encodes a member of the intermediate filament family which contains an N-terminal head domain, followed by a central coiled-coil region and a short C-terminal tail. The protein is highly expressed in skeletal and cardiac muscle. The protein links the dystrophin associated protein complex (DAPC) to desmin filaments in muscle and may have a structural role in striated muscle. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jun 2009]

The c.1147C>T (p.R383W) alteration is located in exon 2 (coding exon 2) of the SYNC gene. This alteration results from a C to T substitution at nucleotide position 1147, causing the arginine (R) at amino acid position 383 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
