Variant summary

Our verdict is Uncertain significance. Variant got 1 ACMG points: 3P and 2B. PM2PP2BP4_Moderate

The NM_001352186.2(ANKS1B):ā€‹c.2980A>Gā€‹(p.Ile994Val) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00000496 in 1,613,916 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (ā˜…). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. I994S) has been classified as Uncertain significance.

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=0.14921921).

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 19, 2024The c.2980A>G (p.I994V) alteration is located in exon 19 (coding exon 19) of the ANKS1B gene. This alteration results from a A to G substitution at nucleotide position 2980, causing the isoleucine (I) at amino acid position 994 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
