Chirag Patel gene: ZMIZ1 was added gene: ZMIZ1 was added to Intellectual disability, syndromic and non-syndromic_GHQ_VCGS. Sources: Literature Mode of inheritance for gene: ZMIZ1 was set to MONOALLELIC, autosomal or pseudoautosomal, NOT imprinted Publications for gene: ZMIZ1 were set to PubMed: 30639322 Phenotypes for gene: ZMIZ1 were set to Neurodevelopmental disorder with dysmorphic facies and distal skeletal anomalies; OMIM #618659 Review for gene: ZMIZ1 was set to GREEN Added comment: 28 families with spectrum of neurodevelopmental features (including ID, ASD, and ADHD) due to de novo ZNF292 variants (1 family inherited). No functional evidence of specific variants, but ZNF292 is highly expressed in the developing human brain. 14 unrelated patients with neurodevelopmental disorder with dysmorphic facies and distal skeletal anomalies, and de novo heterozygous mutations in the ZMIZ1 gene. Transfection of 3 variants (T300M, c.3112dupA, and K91R) into HEK293T cells resulted in decreased induction of luciferase activity compared to wildtype (although the change for K91R was not statistically significant), suggesting impaired coactivation activity of the mutant proteins. Electroporation of these 3 mutants into progenitor cells in the ventricular zone of embryonic mice cortices resulted in defective neuronal migration to the cortex, as well as morphologic abnormalities of the neurons manifest as rounded cells with aberrantly oriented processes. These findings suggested that the ZMIZ1 mutations disrupted proper neuronal polarization and neuronal migration in the developing cortex. Functional studies of the other variants and additional studies of patient cells were not performed. Sources: Literature |
