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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 08, 2024The c.1897A>C (p.K633Q) alteration is located in exon 15 (coding exon 15) of the RHPN2 gene. This alteration results from a A to C substitution at nucleotide position 1897, causing the lysine (K) at amino acid position 633 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
