Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the TRDN gene is commonly pathogenic or not.

In the table, we include only reliable ClinVar variants with their consequences to MANE Select, Mane Plus Clinical transcripts, or transcripts with TSL equals 1. Click the count to view the source variants.

Warning: slight differences between displayed counts and the number of variants in ClinVar may occur, primarily due to (1) the application of a different transcript and/or consequence by our variant effect predictor or (2) differences in clinical significance: we classify Benign/Likely benign variants as Likely benign and Pathogenic/Likely pathogenic variants as Likely pathogenic.

• Function: FUNCTION: Contributes to the regulation of lumenal Ca2+ release via the sarcoplasmic reticulum calcium release channels RYR1 and RYR2, a key step in triggering skeletal and heart muscle contraction. Required for normal organization of the triad junction, where T-tubules and the sarcoplasmic reticulum terminal cisternae are in close contact (By similarity). Required for normal skeletal muscle strength. Plays a role in excitation- contraction coupling in the heart and in regulating the rate of heart beats. {ECO:0000250|UniProtKB:E9Q9K5, ECO:0000269|PubMed:22422768}.
• Disease: DISEASE: Ventricular tachycardia, catecholaminergic polymorphic, 5, with or without muscle weakness (CPVT5) [MIM:615441]: An arrhythmogenic disorder characterized by stress-induced, bidirectional ventricular tachycardia that may degenerate into cardiac arrest and cause sudden death. Patients present with recurrent syncope, or sudden death after physical activity or emotional stress. Some patients have muscle weakness. CPVT5 inheritance is autosomal recessive. {ECO:0000269|PubMed:22422768}. Note=The disease is caused by mutations affecting the gene represented in this entry.
