Variant summary
Our verdict is Benign. Variant got -20 ACMG points: 0P and 20B. BP4_StrongBP6_Very_StrongBA1
The NM_001232.4(CASQ2):āc.196A>Gā(p.Thr66Ala) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.308 in 1,612,466 control chromosomes in the GnomAD database, including 79,340 homozygotes. In-silico tool predicts a benign outcome for this variant. 14/20 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Benign (ā ā ). Another nucleotide change resulting in same amino acid change has been previously reported as Benignin ClinVar. Synonymous variant affecting the same amino acid position (i.e. T66T) has been classified as Likely benign.

Catecholaminergic polymorphic ventricular tachycardia 2 Benign:5
Benign, criteria provided, single submitter | clinical testing | Illumina Laboratory Services, Illumina | Apr 27, 2017 | This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). Publications were found based on this search. The evidence from the literature, in combination with allele frequency data from public databases where available, was sufficient to rule this variant out of causing disease. Therefore, this variant is classified as benign. - |

Cardiovascular phenotype Benign:1
Benign, criteria provided, single submitter | clinical testing | Ambry Genetics | Mar 23, 2015 | This alteration is classified as benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. - |
