Green List (high evidence)

Comment on list classification: There is sufficient evidence to promote this gene to Green at the next GMS panel update.
Created: 2 Sep 2025, 10:58 a.m. | Last Modified: 2 Sep 2025, 10:58 a.m.
Panel Version: 8.25
Total of 14 individuals from 7 unrelated families with biallelic loss of function variants in ELFN1 and a neurodevelopmental disorder comprising DD/ID ranging from moderate to severe (13/13) and epilepsy (12/13). Other features included dysmorphic features, behavioural disturbances, ADHD, ASD, hypotonia, muscle weakness, ataxia. Knockout and haploinsufficiency studies in mice resulted in detectable phenotypes compatible with ELFN1 deficiency disorder.
