GNB2 is not yet associated with any phenotype in OMIM, but has a 'confirmed' disease confidence rating for 'GNB2-related developmental disorder (monoallelic)' in G2P.

At least 14 unrelated individuals with de novo monoallelic variants, including 5 recurrent variants in 13 individuals (PMIDs: 31698099; 33971351; 34183358). All patients (except one fetus owing to termination of pregnancy) have DD/ID of variable severity (mild to severe) which appeared to correlate with the variant each individual harboured. Other variable features include non-specific facial dysmorphism, hypotonia, and autistic behaviour.
