Genes affected
TECRL (HGNC:27365): (trans-2,3-enoyl-CoA reductase like) The protein encoded by this gene contains a ubiquitin-like domain in the N-terminal region, three transmembrane segments and a C-terminal 3-oxo-5-alpha steroid 4-dehydrogenase domain. The protein belongs to the steroid 5-alpha reductase family. Mutations in this gene result in ventricular tachycardia, catecholaminergic polymorphic, 3. [provided by RefSeq, Apr 2017]

Submissions by phenotype

Cardiovascular phenotype Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 11, 2024The p.K340R variant (also known as c.1019A>G), located in coding exon 12 of the TECRL gene, results from an A to G substitution at nucleotide position 1019. The lysine at codon 340 is replaced by arginine, an amino acid with highly 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. -
