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

Classification made for transcript

Verdict is Benign. Variant got -19 ACMG points.

PP2
Missense variant in gene, where missense usually causes diseases (based on misZ statistic), ANK3. . Gene score misZ 2.7937 (greater than the threshold 3.09). Trascript score misZ 5.3471 (greater than threshold 3.09). GenCC has associacion of gene with intellectual disability, Tourette syndrome, intellectual disability-hypotonia-spasticity-sleep disorder syndrome.
BP4
Computational evidence support a benign effect (MetaRNN=0.0064894557).
BP6
Variant 10-60070826-T-C is Benign according to our data. Variant chr10-60070826-T-C is described in ClinVar as [Likely_benign]. Clinvar id is 210138.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
BS1
Variant frequency is greater than expected in population mid. gnomad4_exome allele frequency = 0.00464 (6785/1461802) while in subpopulation MID AF= 0.0161 (93/5768). AF 95% confidence interval is 0.0135. There are 29 homozygotes in gnomad4_exome. There are 3449 alleles in male gnomad4_exome subpopulation. Median coverage is 34. This position pass quality control queck.
BS2
