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]

ACMG classification

Our verdict: Benign. The variant received -19 ACMG points.

• BP4: Computational evidence support a benign effect (REVEL=0.082).
• BP6: Variant 4-113330378-C-T is Benign according to our data. Variant chr4-113330378-C-T is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 238576.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BP7: Synonymous conserved (PhyloP=-0.101 with no splicing effect.
• BS1: Variant frequency is greater than expected in population mid. GnomAdExome4 allele frequency = 0.000163 (238/1461880) while in subpopulation MID AF = 0.000693 (4/5768). AF 95% confidence interval is 0.000236. There are 0 homozygotes in GnomAdExome4. There are 127 alleles in the male GnomAdExome4 subpopulation. Median coverage is 31. This position passed quality control check.
• BS2: High AC in GnomAd4 at 19 AD,Unknown gene.
