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.835G>T (p.D279Y) alteration is located in exon 7 (coding exon 7) of the CORO2B gene. This alteration results from a G to T substitution at nucleotide position 835, causing the aspartic acid (D) at amino acid position 279 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
