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 c.984G>T variant (also known as p.L328L), located in coding exon 12 of the TECRL gene, results from a G to T substitution at nucleotide position 984. This nucleotide substitution does not change the leucine at codon 328. This nucleotide position is not well conserved in available vertebrate species. In silico splice site analysis predicts that this alteration may weaken the native splice acceptor site. Based on the available evidence, the clinical significance of this variant remains unclear. -
