RHOBTB2
Chr 8ADRho related BTB domain containing 2
Regulator of cell proliferation and apoptosis (PubMed:21801820). It likely functions as a substrate-adapter that recruits key substrates, e.g. MSI2, to CUL3-based ubiquitin ligase complexes for degradation (PubMed:15107402, PubMed:27941885). Required for MSI2 ubiquitination and degradation (PubMed:27941885)

Moderately missense-constrained (top ~2.5%)
This gene — mechanism propensity
This gene has evidence for multiple mechanisms of pathogenicity (dominant-negative and gain-of-function). Both the Badonyi & Marsh prediction and the broader genomic evidence point to dominant-negative as the predominant mechanism. Different variants in this gene may act through different mechanisms — interpret in context of the specific variant.
Note: In-silico variant effect predictors (SIFT, PolyPhen, REVEL, CADD) may underestimate pathogenicity of missense variants in genes with GOF or DN mechanisms. Consider functional evidence and clinical context.
