Intellectual disability - microarray and sequencing
Gene: ZMYND8This gene is not currently associated with a disease phenotype in OMIM, but checked PMID:35916866 to make sure it is the same gene listed in the publication as on this panel and it is, so added the gene-checked tagCreated: 16 Oct 2023, 8:15 p.m. | Last Modified: 16 Oct 2023, 8:15 p.m.

As reviewed by Konstantinos Varvagiannis, PMID:35916866 reported intellectual disability in10 out of 11 unrelated cases, of which one patient had profound ID and two had moderate ID.
This gene has not yet been associated with phenotypes in OMIM, but has been reported in Gene2Phenotype (with 'moderate' rating in the DD panel).Created: 22 May 2023, 11:58 a.m. | Last Modified: 22 May 2023, 11:58 a.m.

Publications
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.
