Genes affected

CORO2B (HGNC:2256): (coronin 2B) Enables talin binding activity and vinculin binding activity. Acts upstream of or within several processes, including negative regulation of cell-substrate adhesion; regulation of actin cytoskeleton organization; and regulation of establishment of protein localization. Located in focal adhesion. [provided by Alliance of Genome Resources, Apr 2022]

The c.1025A>G (p.K342R) alteration is located in exon 9 (coding exon 9) of the CORO2B gene. This alteration results from a A to G substitution at nucleotide position 1025, causing the lysine (K) at amino acid position 342 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
