A915G Summary

KCNH2 A915G was found in 0 papers (see below) with a total of 0 carriers: 0 had LQT2. A915G is not present in gnomAD. A915G has been functionally characterized in 0 papers. This residue is located in a Non_Hotspot region for LQT2.

In silico predictions, functional data (if available), and location in structure are equivalent to observing 9 individuals unaffected with LQT2 and 1 individuals affected with LQT2.

A915G 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.

A915G has 30 neighbors (found in individuals) within 15 ångströms

A residue within a folded protein on average has nearest neighbors that fall roughly into two shells: a "nearest" neighbor around 5-6 angstroms and a second shell around 11 angstroms. NOTE: some residues appear multiple times at different distances. This results from the fact that the functional Kv11.1 channel is a homotetramer and occasionally the same residue from multiple subunits is present within the 15A window. All variants shown in the rightmost column have been observed in at least one individual in the literature or gnomAD.
