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 GeneticsFeb 22, 2023The c.1573G>A (p.D525N) alteration is located in exon 13 (coding exon 13) of the RHPN2 gene. This alteration results from a G to A substitution at nucleotide position 1573, causing the aspartic acid (D) at amino acid position 525 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
