Intellectual disability syndromic and non-syndromic v0.5713 DENND5B Elena Savva Publications for gene: DENND5B were set to
Intellectual disability syndromic and non-syndromic v0.5713 DENND5B Elena Savva Mode of pathogenicity for gene: DENND5B was changed from None to None
Intellectual disability syndromic and non-syndromic v0.5290 DENND5B Zornitza Stark Marked gene: DENND5B as ready
Intellectual disability syndromic and non-syndromic v0.5290 DENND5B Zornitza Stark Gene: dennd5b has been classified as Green List (High Evidence).
Intellectual disability syndromic and non-syndromic v0.5290 DENND5B Zornitza Stark Phenotypes for gene: DENND5B were changed from Neurodevelopmental disorder with white matter anomalies to Neurodevelopmental disorder with white matter anomalies, MONDO:0700092, DENND5B-related
Intellectual disability syndromic and non-syndromic v0.5264 DENND5B Chirag Patel Classified gene: DENND5B as Green List (high evidence)
Intellectual disability syndromic and non-syndromic v0.5264 DENND5B Chirag Patel Gene: dennd5b has been classified as Green List (High Evidence).
Intellectual disability syndromic and non-syndromic v0.5263 DENND5B Chirag Patel gene: DENND5B was added
gene: DENND5B was added to Intellectual disability syndromic and non-syndromic. Sources: Other
Mode of inheritance for gene: DENND5B was set to MONOALLELIC, autosomal or pseudoautosomal, NOT imprinted
Phenotypes for gene: DENND5B were set to Neurodevelopmental disorder with white matter anomalies
Review for gene: DENND5B was set to GREEN
gene: DENND5B was marked as current diagnostic
Added comment: ESHG 2023:
7 patients/7 families with de novo DENND5B variants (6 missense, 1 splice)
DD/ID (mod/profound)(7/7), white matter anomalies (6/7) hypotonia, epilepsy (3/7)

DENND5B acts as:
-GEF for activation of RAB proteins which are involved in membrane trafficking and neurotransmitter release
-regulator of lipid absorption and homeostasis

Functional studies showed loss of expression of DENND5B in fibroblasts, abnormal vesicle trafficking, and impaired lipid uptake and intracellular distribution
