Intellectual disability syndromic and non-syndromic v1.656 PGBD5 Zornitza Stark Marked gene: PGBD5 as ready
Intellectual disability syndromic and non-syndromic v1.656 PGBD5 Zornitza Stark Gene: pgbd5 has been classified as Green List (High Evidence).
Intellectual disability syndromic and non-syndromic v1.656 PGBD5 Zornitza Stark Classified gene: PGBD5 as Green List (high evidence)
Intellectual disability syndromic and non-syndromic v1.656 PGBD5 Zornitza Stark Gene: pgbd5 has been classified as Green List (High Evidence).
Intellectual disability syndromic and non-syndromic v1.655 PGBD5 Zornitza Stark gene: PGBD5 was added
gene: PGBD5 was added to Intellectual disability syndromic and non-syndromic. Sources: Literature
Mode of inheritance for gene: PGBD5 was set to BIALLELIC, autosomal or pseudoautosomal
Publications for gene: PGBD5 were set to 41533792
Phenotypes for gene: PGBD5 were set to Neurodevelopmental disorder with seizures, hypotonia, and variable spasticity, MIM# 621482
Review for gene: PGBD5 was set to GREEN
Added comment: 10 individuals reported from 5 consanguineous families with bi-allelic variants in this gene and global developmental delay with impaired intellectual development, delayed motor skills, and motor abnormalities. Affected individuals were unable to speak or walk due to peripheral spasticity, ataxia, or hypotonia, and developed early-onset seizures. Additional features included dysmorphic facies, short stature, and brain imaging abnormalities, such as thin corpus callosum and cerebellar atrophy.

Pgbd5-null mice were runted and had significantly smaller brains compared to wildtype. Mutant mice showed increased locomotor activity, reduced anxiety-like behavior, impaired motor coordination, increased susceptibility to seizures, and decreased cortical volume on brain MRI. Analysis of neurons derived from Pgbd5-null mouse brains showed reduced DNA breakage and repair in postmitotic neuronal precursors during cortical development compared to controls.
