1 BrS1 · 0 LQT3 · 0 unaffected
Variant features alone are equivalent to phenotyping 5 individuals for Brugada syndrome and 0 individuals for LQT3.
In silico predictors
| PROVEAN | PolyPhen-2 | BLAST-PSSM | REVEL | Penetrance Density BrS (%) | Penetrance Density LQT3 (%) |
|---|---|---|---|---|---|
| -6.24 | 1 | -4.76 | 0.996 | 83 | 5 |
PROVEAN scores below -2 suggest deleterious impact. REVEL scores above 0.5–0.75 are often interpreted as likely pathogenic. PolyPhen-2 scores above 0.85 are typically pathogenic. Penetrance density summarises neighbouring residue risk (Kroncke et al. 2019).
Reported carrier data

Totals may differ from individual publications due to duplicate patients removed during curation.
Functional data
Peak and late/persistent current values are relative to wild-type (100% indicates no change). V1/2 activation and inactivation denote the membrane potentials (mV) at which half-maximal current is achieved.
