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]

The p.M333K variant (also known as c.998T>A), located in coding exon 12 of the TECRL gene, results from a T to A substitution at nucleotide position 998. The methionine at codon 333 is replaced by lysine, an amino acid with similar properties. This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
