Genes affected

TRDN (HGNC:12261): (triadin) This gene encodes an integral membrane protein found in skeletal and cardiac muscle. The encoded protein plays a role in skeletal muscle excitation-contraction coupling as part of the calcium release complex and is required for normal skeletal muscle strength. This protein indirectly links triads and microtubules in skeletal muscle. Mutations in this gene are associated with cardiac arrythmia syndrome and some variants in this gene may be associated with sudden cardiac death. [provided by RefSeq, May 2022]

The c.1472-12G>A variant in TRDN has not been previously reported in individuals with cardiomyopathy, but has been identified in 20/65850 European chromosomes b y the Exome Aggregation Consortium (ExAC, http://exac.broadinstitute.org; dbSNP rs375364108). This variant is located in the 3' splice region. Computational too ls do not suggest an impact to splicing. However, this information is not predic tive enough to rule out pathogenicity. In summary, the clinical significance of the c.1472-12G>A variant is uncertain.
