Genetic Epilepsy v0.2030 B3GALNT2 Zornitza Stark Gene: b3galnt2 has been classified as Green List (High Evidence).
Genetic Epilepsy v0.2030 B3GALNT2 Zornitza Stark Classified gene: B3GALNT2 as Green List (high evidence)
Genetic Epilepsy v0.2030 B3GALNT2 Zornitza Stark Gene: b3galnt2 has been classified as Green List (High Evidence).
Genetic Epilepsy v0.2028 B3GALNT2 Lilian Downie gene: B3GALNT2 was added
gene: B3GALNT2 was added to Genetic Epilepsy. Sources: Expert list
Mode of inheritance for gene: B3GALNT2 was set to BIALLELIC, autosomal or pseudoautosomal
Publications for gene: B3GALNT2 were set to PMID: 29791932, PMID: 29273094, PMID: 35127920
Phenotypes for gene: B3GALNT2 were set to Muscular dystrophy-dystroglycanopathy (congenital with brain and eye anomalies), type A, 11 MIM#615181
Review for gene: B3GALNT2 was set to GREEN
Added comment: Severe congenital muscular dystrophy and ID phenotype. Seizures not consistent feature with early phenotypic reports
PMID: 29791932 epileptic encephalopathy
PMID: 29273094 5 individuals with ID and seizures from single large consanguineous family but they had no or mild muscle symptoms so quite different from previously reported phenotype
PMID: 35127920 not a great article but does have a table summarising the previous cases and 9/21 had seizures.

Genetic Epilepsy v0.676 GALNT2 Zornitza Stark Marked gene: GALNT2 as ready
Genetic Epilepsy v0.676 GALNT2 Zornitza Stark Gene: galnt2 has been classified as Green List (High Evidence).
Genetic Epilepsy v0.676 GALNT2 Zornitza Stark Classified gene: GALNT2 as Green List (high evidence)
Genetic Epilepsy v0.676 GALNT2 Zornitza Stark Gene: galnt2 has been classified as Green List (High Evidence).
Genetic Epilepsy v0.675 GALNT2 Zornitza Stark gene: GALNT2 was added
gene: GALNT2 was added to Genetic Epilepsy. Sources: Literature
Mode of inheritance for gene: GALNT2 was set to BIALLELIC, autosomal or pseudoautosomal
Publications for gene: GALNT2 were set to 32293671
Phenotypes for gene: GALNT2 were set to Congenital disorder of glycosylation
Review for gene: GALNT2 was set to GREEN
Added comment: Seven individuals from four families reported with bi-allelic LOF variants and global developmental delay, intellectual disability with language deficit, autistic features, behavioural abnormalities, epilepsy, chronic insomnia, white matter changes on brain MRI, dysmorphic features, decreased stature, and decreased high density lipoprotein cholesterol levels. Rodent (mouse and rat) models of GALNT2-CDG recapitulated much of the human phenotype, including poor growth and neurodevelopmental abnormalities.
