Summaries for Neurodevelopmental Disorder with Severe Motor Impairment and...

NIH Rare Diseases : 54 Neurodevelopmental disorder with severe motor impairment and absent language (NEDMIAL) is a rare condition caused by a change in the DexH-box helicase 30 (DHX30) gene. The most common signs and symptoms are severe intellectual, speech and walking impairment. Infants with the disorder have low muscle tone, delayed mental and motor skills, and problems feeding. Many children with the disorder are non-verbal, although some use a few words. Walking is difficult for children with this rare disorder. Children who walk independently have an unsteady gait. Additional symptoms vary, but may include autistic features, behavior challenges, sleep disorder, seizures, hyper-flexible joints, involuntary movements, distinctive facial features, and strabismus.

MalaCards based summary : Neurodevelopmental Disorder with Severe Motor Impairment and Absent Language, is also known as nedmial. An important gene associated with Neurodevelopmental Disorder with Severe Motor Impairment and Absent Language is DHX30 (DExH-Box Helicase 30). Affiliated tissues include brain, and related phenotypes are seizures and high palate

OMIM : 58 NEDMIAL is a neurodevelopmental disorder characterized by severely delayed psychomotor development and hypotonia apparent from early infancy, resulting in feeding difficulties, ataxic gait or inability to walk, minimal or absent speech development, and severe intellectual disability, often with behavioral abnormalities, such as hand-flapping. Additional common features may include sleep disorder, nonspecific dysmorphic facial features, and joint hyperlaxity (summary by Lessel et al., 2017). (617804)

UniProtKB/Swiss-Prot : 76 Neurodevelopmental disorder with severe motor impairment and absent language: An autosomal dominant neurodevelopmental disorder characterized by global developmental delay, intellectual disability, severe speech impairment and gait abnormalities.
