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 p.T198A variant (also known as c.592A>G), located in coding exon 7 of the TRDN gene, results from an A to G substitution at nucleotide position 592. The threonine at codon 198 is replaced by alanine, an amino acid with similar properties. This amino acid position is conserved. In addition, this alteration is predicted to be tolerated by in silico analysis. Based on the available evidence, the clinical significance of this alteration remains unclear. -

p.Thr198Ala in exon 7 of TRDN: This variant is not expected to have clinical sig nificance due to a lack of conservation across species, including mammals. Of no te, >5 mammals have an alanine (Ala) at this position despite high nearby amino acid conservation. In addition, computational prediction tools do not suggest a high likelihood of impact to the protein. -
