Genes affected

RAPGEF3 (HGNC:16629): (Rap guanine nucleotide exchange factor 3) Enables guanyl-nucleotide exchange factor activity and protein domain specific binding activity. Involved in several processes, including positive regulation of protein modification process; regulation of actin cytoskeleton organization; and regulation of syncytium formation by plasma membrane fusion. Located in filopodium; lamellipodium; and microvillus. Colocalizes with cortical actin cytoskeleton and plasma membrane. Biomarker of congestive heart failure.

Ambry Genetics

Nov 17, 2023

The c.1886G>A (p.R629H) alteration is located in exon 19 (coding exon 19) of the RAPGEF3 gene. This alteration results from a G to A substitution at nucleotide position 1886, causing the arginine (R) at amino acid position 629 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
