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.

ClinVar contains an entry for this variant (Variation ID: 1006731). This variant is present in population databases (no rsID available, gnomAD 0.0009%). This sequence change replaces threonine, which is neutral and polar, with arginine, which is basic and polar, at codon 1479 of the ANK2 protein (p.Thr1479Arg). (less)
