Intellectual disability syndromic and non-syndromic v0.5214 | GATAD2A |
Bryony Thompson gene: GATAD2A was added gene: GATAD2A was added to Intellectual disability syndromic and non-syndromic. Sources: Literature Mode of inheritance for gene: GATAD2A was set to MONOALLELIC, autosomal or pseudoautosomal, NOT imprinted Publications for gene: GATAD2A were set to https://doi.org/10.1016/j.xhgg.2023.100198; 17565372 Phenotypes for gene: GATAD2A were set to Neurodevelopmental disorder, MONDO:0700092, GATAD2A-related Review for gene: GATAD2A was set to GREEN Added comment: https://doi.org/10.1016/j.xhgg.2023.100198 - Five unrelated individuals with a neurodevelopmental disorder identified with 3 missense & 2 LoF (4 de novo & 1 unknown inheritance). The shared clinical features with variable expressivity include global developmental delay (4/4), craniofacial dysmorphism (3/5), structural brain defects (2/3), musculoskeletal anomalies (3/5), vision/hearing defects (2/3), gastrointestinal/renal defects (2/3). Loss of function is the expected mechanism of disease. In vitro assays of one of the missense variants (p.Cys420Tyr) demonstrates disruption of GATAD2A integration with CHD3, CHD4, and CHD5 PMID: 17565372 - null mouse model is embryonic lethal.

Intellectual disability syndromic and non-syndromic v0.4895 | ZMYND8 |
Konstantinos Varvagiannis gene: ZMYND8 was added gene: ZMYND8 was added to Intellectual disability syndromic and non-syndromic. Sources: Literature Mode of inheritance for gene: ZMYND8 was set to MONOALLELIC, autosomal or pseudoautosomal, imprinted status unknown Publications for gene: ZMYND8 were set to 35916866; 32530565 Phenotypes for gene: ZMYND8 were set to Delayed speech and language development; Motor delay; Intellectual disability; Abnormality of cardiovascular system morphology; Hearing abnormality; Abnormality of vision; Abnormality of the face; Seizures Penetrance for gene: ZMYND8 were set to unknown Review for gene: ZMYND8 was set to GREEN Added comment: Dias et al (2022 - PMID: 35916866) describe the phenotype of 11 unrelated individuals with monoallelic de novo (or suspected de novo) missense (N=9) or truncating (N=2) ZMYND8 variants. One of these subjects was previously reported by Suzuki et al (2020 - PMID: 32530565). Features included speech delay/language difficulties (9/11), motor delay (9/11), ID (in 10/11 - profound in 1, moderate in 2), CHD (7/11 - PDA, VSD, ASD, pulmonary stenosis, etc), hearing or vision impairment (7/11). Seizures were reported in few (in text 5/11, table 2/11). Variable non-familial facial features were present in (9/11). As the authors discuss, ZMYND8 encodes a multidomain protein playing a role in transcription regulation, chromatin remodeling, regulation of super enhancers, DNA damage response/tumor suppression. The protein is broadly expressed in brain and shows highest expression in early development. Molecular modeling and/or a yeast two-hybrid system were suggestive of disrupted interaction of ZMYND8 with Drebrin (missense variants in PWWP domain) or GATAD2A (variants in MYND domain). Neuronal Zmynd8 knockdown in Drosophila resulted in deficits in habituation learning. Sources: Literature |
