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]

Catecholaminergic polymorphic ventricular tachycardia 1 Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Aug 18, 2020 | This sequence change results in a premature translational stop signal in the TRDN gene (p.Gln729*). While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last one amino acid of the TRDN protein. This variant is present in population databases (rs769741426, ExAC 0.04%). This variant has not been reported in the literature in individuals with TRDN-related conditions. Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. - |
