Genes affected

ABI3BP (HGNC:17265): (ABI family member 3 binding protein) Predicted to enable actin filament binding activity and glycosaminoglycan binding activity. Predicted to be involved in regulation of actin cytoskeleton reorganization; regulation of dendritic spine morphogenesis; and regulation of postsynaptic density assembly. Predicted to act upstream of or within extracellular matrix organization and positive regulation of cell-substrate adhesion. Located in extracellular space. Colocalizes with collagen-containing extracellular matrix. [provided by Alliance of Genome Resources, Apr 2022]

The c.2491G>T (p.G831W) alteration is located in exon 29 (coding exon 29) of the ABI3BP gene. This alteration results from a G to T substitution at nucleotide position 2491, causing the glycine (G) at amino acid position 831 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
