Genes affected
ANKS1B (HGNC:24600): (ankyrin repeat and sterile alpha motif domain containing 1B) This gene encodes a multi-domain protein that is predominantly expressed in brain and testis. This protein interacts with amyloid beta protein precursor (AbetaPP) and may have a role in normal brain development, and in the pathogenesis of Alzheimer's disease. Expression of this gene has been shown to be elevated in patients with pre-B cell acute lymphocytic leukemia associated with t(1;19) translocation. Alternatively spliced transcript variants encoding different isoforms (some with different subcellular localization, PMID:15004329) have been described for this gene. [provided by RefSeq, Aug 2011]

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 1 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), ANKS1B. . Gene score misZ 2.9457 (greater than the threshold 3.09). Trascript score misZ 3.7643 (greater than threshold 3.09). GenCC has associacion of gene with complex neurodevelopmental disorder.
BP4
Computational evidence support a benign effect (MetaRNN=0.14984307).

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 15, 2023The c.2845G>A (p.D949N) alteration is located in exon 18 (coding exon 18) of the ANKS1B gene. This alteration results from a G to A substitution at nucleotide position 2845, causing the aspartic acid (D) at amino acid position 949 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
