0 BrS1 · 0 LQT3 · 1 unaffected
Variant features alone are equivalent to phenotyping 0 individuals for Brugada syndrome and 0 individuals for LQT3.
In silico predictors
| PROVEAN | PolyPhen-2 | BLAST-PSSM | REVEL | Penetrance Density BrS (%) | Penetrance Density LQT3 (%) |
|---|---|---|---|---|---|
| -4.95 | 0.9 | -1.7 | 0.882 | 2 | 2 |
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
| Source | Year | Carriers | Unaffected | LQT3 | BrS1 | Other | Other Disease |
|---|---|---|---|---|---|---|---|
| Literature, cohort, and gnomAD | – | 1 | 1 | 0 | 0 | – | |
| Variant features alone | – | 15 | 15 | 0 | 0 | – | – |
Totals may differ from individual publications due to duplicate patients removed during curation.
