KCNH2 Variant P151X Detail
P151X is %.
This variant was found in a total of 1 carriers in 0 papers or gnomAD (version 4),
1 had LQTS.
P151X is not present in gnomAD.
We have tested the trafficking efficiency of this variant, 0% of WT
with a standard error of 3%; in our analysis we used SE < 20% as 'high quality'.
Approximately below 50% of WT is considered PS3 moderate and below 30% is PS3 strong.
P151X has not been functionally characterized.
This residue is located in a None region for LQT2.
PROVEAN scores less than -2 are considered deleterious. REVEL scores higher than 0.5 or 0.75 are 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.
BLAST-PSSM reflects the evolutionary conservation of residue substitutions, more negative numbers indicate
fewer observations of the specific substitution than is expected. Penetrance density is our previously published method
to calculate the average LQTS probability density in a shell of residues surrounding a residue of interest
(
).
Summary totals might not agree with the literature table because of duplicate patients, which were excluded from the
total counts. We do not distinguish here between multiple missense codons. Missense variants are combined across
degenerate codon substitutions since codon-level data were not consistently available for curation.
