Genes affected

ABI2 (HGNC:24011): (abl interactor 2) Enables several functions, including SH3 domain binding activity; identical protein binding activity; and ubiquitin protein ligase binding activity. Contributes to small GTPase binding activity. Involved in Rac protein signal transduction; positive regulation of cellular component organization; and zonula adherens assembly. Acts upstream of or within peptidyl-tyrosine phosphorylation. Located in several cellular components, including filopodium tip; lamellipodium; and nucleoplasm. Part of SCAR complex. Is active in adherens junction. Colocalizes with actin filament. [provided by Alliance of Genome Resources, Apr 2022]

Apr 11, 2023

The c.344A>G (p.N115S) alteration is located in exon 3 (coding exon 3) of the ABI2 gene. This alteration results from a A to G substitution at nucleotide position 344, causing the asparagine (N) at amino acid position 115 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
