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]
ANK2-AS1 (HGNC:40076): (ANK2 antisense RNA 1)

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 2 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
PP2
Missense variant in gene, where missense usually causes diseases (based on misZ statistic), ANK2. . Gene score misZ 1.9641 (greater than the threshold 3.09). Trascript score misZ 4.2513 (greater than threshold 3.09). GenCC has associacion of gene with heart conduction disease, Brugada syndrome, long QT syndrome, complex neurodevelopmental disorder, cardiac arrhythmia, ankyrin-B-related, catecholaminergic polymorphic ventricular tachycardia.
BP4
Computational evidence support a benign effect (MetaRNN=0.35247678).
