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]

Catecholaminergic polymorphic ventricular tachycardia 3

Pathogenic:2

Likely pathogenic, criteria provided, single submitter	clinical testing	Victorian Clinical Genetics Services, Murdoch Childrens Research Institute	Mar 31, 2022	Based on the classification scheme VCGS_Germline_v1.3.4, this variant is classified as Likely Pathogenic. Following criteria are met: 0102 - Loss of function is a known mechanism of disease in this gene and is associated with catecholaminergic polymorphic ventricular tachycardia 3 (MIM#614021). (I) 0106 - This gene is associated with autosomal recessive disease. (I) 0115 - Variants in this gene are known to have variable expressivity. This gene has been described to be associated with overlapping clinical features of both long QT syndrome and CPVT (PMID: 27861123). (I) 0200 - Variant is predicted to result in a missense amino acid change from arginine to glutamine. (I) 0251 - This variant is heterozygous. (I) 0304 - Variant is present in gnomAD <0.01 for a recessive condition (v2: 7 heterozygotes, 0 homozygotes). (SP) 0309 - An alternative amino acid change at the same position has been observed in gnomAD (v2: 1 heterozygote, 0 homozygotes). (I) 0502 - Missense variant with conflicting in silico predictions and uninformative conservation. (I) 0604 - Variant is not located in an established domain, motif, hotspot or informative constraint region. (I) 0705 - No comparable missense variants have previous evidence for pathogenicity. (I) 0802 - This variant has moderate previous evidence of pathogenicity in unrelated individuals. It has been reported in one compound heterozygous individual with CPVT (PMID: 30790670), and two homozygous individuals who presented with cardiac arrest, stress-induced atrial and ventricular tachycardia, and QT prolongation upon adrenergic stimulation, and who were both diagnosed with long QT syndrome (PMID: 27861123). (SP) 0905 - No published segregation evidence has been identified for this variant. (I) 1007 - No published functional evidence has been identified for this variant. (I) 1102 - Strong phenotype match for this individual. (SP) 1206 - This variant has been shown to be paternally inherited.
