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]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 06, 2021The c.951T>A (p.F317L) alteration is located in exon 2 (coding exon 2) of the SYNC gene. This alteration results from a T to A substitution at nucleotide position 951, causing the phenylalanine (F) at amino acid position 317 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
