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]

Ambry Genetics

Nov 13, 2023

The c.2774T>C (p.I925T) alteration is located in exon 17 (coding exon 17) of the ANKS1B gene. This alteration results from a T to C substitution at nucleotide position 2774, causing the isoleucine (I) at amino acid position 925 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
