E491G Summary

SCN5A E491G was found in 0 papers (see below) with a total of 1 carrier: 0 had BrS1, 0 had LQT3, and 0 had other disease. E491G is present in 1 out of 249170 alleles in gnomAD (minor allele frequency of 0.000401%). E491G has been functionally characterized in 0 papers. Other variants at the same resdue are E491A .E491D .E491D .E491G .E491K .E491Q .E491V . This residue is located in a Non_Hotspot region for BrS1 and in a Non_Hotspot region for Long QT syndrome.

E491G Predictions

PROVEAN scores less than -2 are considered deleterious. REVEL scores higher than 0.5 or 0.75 is considered likely pathogenic (higher sensitivity with the former cutoff, higher specificity with the latter cutoff). A PolyPhen-2 score of 0.85 or greater is considered likely pathogenic. PAM scores reflect the chemistry difference between WT and variant amino acid (more negative being greater difference between the two). BLAST-PSSM reflects the evolutionary conservation of residue substitutions, more negative numbers indicate fewer observations of the specific substitution than is expected.
