SCN5A A1221V was found in 2 papers (see below) with a total of 5 carriers: 0 had BrS1, 1 had LQT3, and 0 had other disease. A1221V is present in 3 out of 247618 alleles in gnomAD (minor allele frequency of 0.001212%). A1221V has been functionally characterized in 0 papers. Other variants at the same resdue are A1221E .A1221G .A1221P .A1221S .A1221T .A1221V .
This residue is located in a Mild_Hotspot region for BrS1 and in a Mild_Hotspot region for Long QT syndrome.
A1221V Reported Clinical Data

Summary totals might not agree with the literature table because of duplicate patients, which were excluded from the total counts.
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.
A1221V has 48 neighbors within 15 ångströms that have been found in individuals.
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.
