Variant summary
Our verdict is Likely pathogenic. Variant got 9 ACMG points: 9P and 0B. PM1PM2PP2PP3_Strong
The NM_001099404.2(SCN5A):c.5009T>C(p.Ile1670Thr) variant causes a missense change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. I1670V) has been classified as Uncertain significance.

Uncertain significance, criteria provided, single submitter | clinical testing | Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine | Oct 03, 2012 | The Ile1670Thr variant in SCN5A has not been reported in the literature nor prev iously identified by our laboratory. The affected amino acid is highly conserved in evolution, suggesting that a change at this position would impact the protei n. Other computational analyses (biochemical amino acid properties, AlignGVGD, P olyPhen2, and SIFT) also support a disease causing role, though this information is not predictive enough to determine pathogenicity. Additional information is needed to fully assess the clinical significance of the Ile1670Thr variant. - |
