Genes affected

RAP2A (HGNC:9861): (RAP2A, member of RAS oncogene family) Enables GTPase activity; guanyl ribonucleotide binding activity; and magnesium ion binding activity. Involved in several processes, including actin cytoskeleton reorganization; microvillus assembly; and positive regulation of protein autophosphorylation. Acts upstream of or within establishment of protein localization. Located in plasma membrane and recycling endosome membrane. [provided by Alliance of Genome Resources, Apr 2022]

Ambry Genetics

May 18, 2022

The c.5G>A (p.R2H) alteration is located in exon 1 (coding exon 1) of the RAP2A gene. This alteration results from a G to A substitution at nucleotide position 5, causing the arginine (R) at amino acid position 2 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
