Genes affected
ANK2 (HGNC:493): (ankyrin 2) This gene encodes a member of the ankyrin family of proteins that link the integral membrane proteins to the underlying spectrin-actin cytoskeleton. Ankyrins play key roles in activities such as cell motility, activation, proliferation, contact and the maintenance of specialized membrane domains. Most ankyrins are typically composed of three structural domains: an amino-terminal domain containing multiple ankyrin repeats; a central region with a highly conserved spectrin binding domain; and a carboxy-terminal regulatory domain which is the least conserved and subject to variation. The protein encoded by this gene is required for targeting and stability of Na/Ca exchanger 1 in cardiomyocytes. Mutations in this gene cause long QT syndrome 4 and cardiac arrhythmia syndrome. Multiple transcript variants encoding different isoforms have been described. [provided by RefSeq, Dec 2011]

This sequence change replaces proline, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 1501 of the ANK2 protein (p.Pro1501Leu). This variant is present in population databases (rs201071074, gnomAD 0.004%). This missense change has been observed in individual(s) with sudden unexplained cardiac arrest (PMID: 35352813). ClinVar contains an entry for this variant (Variation ID: 457038). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. 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. -

Collection Method: clinical testing

The c.4502C>T (p.P1501L) alteration is located in exon 38 (coding exon 38) of the ANK2 gene. This alteration results from a C to T substitution at nucleotide position 4502, causing the proline (P) at amino acid position 1501 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
