Genes affected

ANK3 (HGNC:494): (ankyrin 3) Ankyrins are a family of proteins that are believed to link the integral membrane proteins to the underlying spectrin-actin cytoskeleton and play key roles in activities such as cell motility, activation, proliferation, contact, and the maintenance of specialized membrane domains. Multiple isoforms of ankyrin with different affinities for various target proteins are expressed in a tissue-specific, developmentally regulated manner. 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. Ankyrin 3 is an immunologically distinct gene product from ankyrins 1 and 2, and was originally found at the axonal initial segment and nodes of Ranvier of neurons in the central and peripheral nervous systems. Multiple transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Feb 2011]

ACMG classification

Our verdict: Benign. The variant received -9 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.51).
• BP7: Synonymous conserved (PhyloP=1.1 with no splicing effect.
• BS1: Variant frequency is greater than expected in population sas. GnomAdExome4 allele frequency = 0.000072 (105/1458198) while in subpopulation SAS AF = 0.0000937 (8/85370). AF 95% confidence interval is 0.0000697. There are 0 homozygotes in GnomAdExome4. There are 65 alleles in the male GnomAdExome4 subpopulation. Median coverage is 29. This position passed quality control check.
