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.1349C>T (p.S450F) alteration is located in exon 11 (coding exon 11) of the RHPN2 gene. This alteration results from a C to T substitution at nucleotide position 1349, causing the serine (S) at amino acid position 450 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
