Genes affected
RAP2C (HGNC:21165): (RAP2C, member of RAS oncogene family) The protein encoded by this gene is a member of the Ras-related protein subfamily of the Ras GTPase superfamily. Members of this family are small GTPases that act as molecular switches to regulate cellular proliferation, differentiation, and apoptosis. This protein has been reported to activate in vitro transcriptional activity of the serum response element. Alternative splicing results in multiple transcript variants.

RAP2C-AS1 (HGNC:40957): (RAP2C antisense RNA 1)

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 20, 2024The c.241G>A (p.V81I) alteration is located in exon 2 (coding exon 1) of the RAP2C gene. This alteration results from a G to A substitution at nucleotide position 241, causing the valine (V) at amino acid position 81 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
