Genes affected
RHOA (HGNC:667): (ras homolog family member A) This gene encodes a member of the Rho family of small GTPases, which cycle between inactive GDP-bound and active GTP-bound states and function as molecular switches in signal transduction cascades. Rho proteins promote reorganization of the actin cytoskeleton and regulate cell shape, attachment, and motility. Overexpression of this gene is associated with tumor cell proliferation and metastasis. Multiple alternatively spliced variants have been identified. [provided by RefSeq, Sep 2015]

Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Oct 05, 2023 | This sequence change replaces glutamic acid, which is acidic and polar, with lysine, which is basic and polar, at codon 47 of the RHOA protein (p.Glu47Lys). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with RHOA-related conditions (PMID: 31570889, 31821646). In at least one individual the variant was observed to be de novo. ClinVar contains an entry for this variant (Variation ID: 695069). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. Experimental studies have shown that this missense change affects RHOA function (PMID: 31570889). For these reasons, this variant has been classified as Pathogenic. - |
