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]

This sequence change falls in intron 20 of the TRDN gene. It does not directly change the encoded amino acid sequence of the TRDN protein. This variant is present in population databases (rs764565579, gnomAD 0.006%). This variant has not been reported in the literature in individuals affected with TRDN-related conditions. ClinVar contains an entry for this variant (Variation ID: 463666). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. 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. -
