Genes affected

KCNJ10 (HGNC:6256): (potassium inwardly rectifying channel subfamily J member 10) This gene encodes a member of the inward rectifier-type potassium channel family, characterized by having a greater tendency to allow potassium to flow into, rather than out of, a cell. The encoded protein may form a heterodimer with another potassium channel protein and may be responsible for the potassium buffering action of glial cells in the brain. Mutations in this gene have been associated with seizure susceptibility of common idiopathic generalized epilepsy syndromes. [provided by RefSeq, Jul 2008]

This sequence change replaces proline, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 102 of the KCNJ10 protein (p.Pro102Leu). This variant is present in population databases (rs372156619, gnomAD 0.04%). This variant has not been reported in the literature in individuals affected with KCNJ10-related conditions. ClinVar contains an entry for this variant (Variation ID: 411158). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
