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]

TRDN-AS1 (HGNC:40592): (TRDN antisense RNA 1)

ACMG classification

Our verdict: Benign. The variant received -13 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.006168872).
• BP6: Variant 6-123503658-A-G is Benign according to our data. Variant chr6-123503658-A-G is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 505274.
• BS1: Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.00163 (248/152132) while in subpopulation AFR AF = 0.0058 (241/41520). AF 95% confidence interval is 0.0052. There are 0 homozygotes in GnomAd4. There are 127 alleles in the male GnomAd4 subpopulation. Median coverage is 31. This position passed quality control check.
• BS2: High Homozygotes in GnomAdExome4 at 2 AD,AR gene
