Genes affected

RHPN2 (HGNC:19974): (rhophilin Rho GTPase binding protein 2) This gene encodes a member of the rhophilin family of Ras-homologous (Rho)-GTPase binding proteins. The encoded protein binds both GTP- and GDP-bound RhoA and GTP-bound RhoB and may be involved in the organization of the actin cytoskeleton. [provided by RefSeq, Apr 2009]

The c.1207C>G (p.Q403E) alteration is located in exon 10 (coding exon 10) of the RHPN2 gene. This alteration results from a C to G substitution at nucleotide position 1207, causing the glutamine (Q) at amino acid position 403 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
