Intellectual disability v3.1624 GNB2 Arina Puzriakova Phenotypes for gene: GNB2 were changed from Intellectual disability to Neurodevelopmental disorder with hypotonia and dysmorphic facies, OMIM:619503
Intellectual disability v3.1519 GNB2 Ivone Leong Tag Q3_21_rating was removed from gene: GNB2.
Intellectual disability v3.1519 GNB2 Sarah Leigh commented on gene: GNB2
Intellectual disability v3.1519 GNB2 Ivone Leong Source Expert Review Green was added to GNB2.
Rating Changed from Amber List (moderate evidence) to Green List (high evidence)
Intellectual disability v3.1163 GNB2 Arina Puzriakova Classified gene: GNB2 as Amber List (moderate evidence)
Intellectual disability v3.1163 GNB2 Arina Puzriakova Added comment: Comment on list classification: There is sufficient evidence to promote this gene to Green at the next GMS panel update.
Intellectual disability v3.1163 GNB2 Arina Puzriakova Gene: gnb2 has been classified as Amber List (Moderate Evidence).
Intellectual disability v3.1162 GNB2 Arina Puzriakova gene: GNB2 was added
gene: GNB2 was added to Intellectual disability. Sources: Literature
Q3_21_rating tags were added to gene: GNB2.
Mode of inheritance for gene: GNB2 was set to MONOALLELIC, autosomal or pseudoautosomal, imprinted status unknown
Publications for gene: GNB2 were set to 31698099; 33971351; 34183358
Phenotypes for gene: GNB2 were set to Intellectual disability
Review for gene: GNB2 was set to GREEN
Added comment: 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.
