Comment on phenotypes: Neurodevelopmental disorder with or without hyperkinetic movements and seizures, autosomal dominant (NDHMSD) is a severe neurodevelopmental disorder characterized by profound developmental delay, severe intellectual disability with absent speech, muscular hypotonia, and a hyperkinetic movement disorder. Additional features may include cortical blindness, generalized cerebral atrophy, and seizures (summary by Lemke et al., 2016). To date, there are 16 unrelated cases with NDHMSD in the literature, Lemke et al. (2016) PMID: 27164704 (a re-evaluation of some previous cases and new cases with NDHMSD) and Chen et al. (2017) PMID: 28228639.
Neurodevelopmental disorder with or without hyperkinetic movements and seizures, autosomal recessive (NDHMSR) is an autosomal recessive neurodevelopmental disorder characterized by severely delayed psychomotor development, severe intellectual disability, and involuntary movements, including stereotypic movements, spasticity, and dystonia. Affected individuals are are usually unable to walk independently and have poor or absent speech. Some patients have intractable seizures (summary by Lemke et al., 2016). The transmission pattern of NDHMSR in the families reported by Lemke et al. (2016) was consistent with autosomal recessive inheritance. PMID: 27164704. To date there are three unrelated consanguineous families with NDHMSR in the literature, Lemke et al. (2016) PMID: 27164704 and Rossi et al. (2017) PMID:28051072.Created: 4 Feb 2018, 5:05 p.m.
Comment on publications: Added publications to support the MOI. For NDHMSR, to date there are three unrelated consanguineous families with NDHMSR in the literature, Lemke et al. (2016) PMID: 27164704 and Rossi et al. (2017) PMID:28051072.
For NDHMSD to date there are 16 unrelated cases with NDHMSD in the literature, Lemke et al. (2016) PMID: 27164704 (a re-evaluation of some previous cases and new cases with NDHMSD) and Chen et al. (2017) PMID: 28228639Created: 4 Feb 2018, 5:02 p.m.
Comment on mode of inheritance: Added publications to support the MOI. For NDHMSR, to date there are three unrelated consanguineous families with NDHMSR in the literature, Lemke et al. (2016) PMID: 27164704 and Rossi et al. (2017) PMID:28051072.
For NDHMSD to date there are 16 unrelated cases with NDHMSD in the literature, Lemke et al. (2016) PMID: 27164704 (a re-evaluation of some previous cases and new cases with NDHMSD) and Chen et al. (2017) PMID: 28228639Created: 4 Feb 2018, 5:01 p.m.
Comment on list classification: changed from Amber to Green as there is now enough evidence in the literature to support the green rating.
