Genes affected

ARHGAP29 (HGNC:30207): (Rho GTPase activating protein 29) Rap1 is a small GTPase that, through effectors, regulates Rho GTPase signaling. These effectors- Rasip1, Radil, and the protein encoded by this gene- translocate to the cell membrane, where they form a multiprotein complex. This complex is necessary for Rap1-induced inhibition of Rho signaling. Defects in this gene may be a cause of nonsyndromic cleft lip with or without cleft palate. [provided by RefSeq, Jun 2016]

The c.3635C>A (p.A1212E) alteration is located in exon 23 (coding exon 22) of the ARHGAP29 gene. This alteration results from a C to A substitution at nucleotide position 3635, causing the alanine (A) at amino acid position 1212 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
