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.2999A>G (p.Y1000C) alteration is located in exon 34 (coding exon 34) of the ABI3BP gene. This alteration results from a A to G substitution at nucleotide position 2999, causing the tyrosine (Y) at amino acid position 1000 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
