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.

The c.2179G>A (p.V727M) alteration is located in exon 21 (coding exon 21) of the RAPGEF3 gene. This alteration results from a G to A substitution at nucleotide position 2179, causing the valine (V) at amino acid position 727 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
