Summaries for Intellectual Developmental Disorder with Hypotonia and Behavioral...

OMIM : 56 Intellectual developmental disorder with hypotonia and behavioral abnormalities (IDDHBA) is a neurodevelopmental disorder characterized by onset of hypotonia and variably impaired global developmental delay in infancy. Affected individuals tend to have learning disability, usually requiring special schooling, as well as behavioral abnormalities, such as autistic features and attention deficit-hyperactivity disorder (ADHD). Additional more variable features may include nonspecific dysmorphic facial features, congenital heart defects, visual or ocular movement anomalies, and poor feeding and/or gastroesophageal reflux (summary by Calpena et al., 2019). (618748)

MalaCards based summary : Intellectual Developmental Disorder with Hypotonia and Behavioral Abnormalities, is also known as iddhba. An important gene associated with Intellectual Developmental Disorder with Hypotonia and Behavioral Abnormalities is CDK8 (Cyclin Dependent Kinase 8). Affiliated tissues include heart, eye and brain, and related phenotypes are intellectual disability and abnormal facial shape

UniProtKB/Swiss-Prot : 73 Intellectual developmental disorder with hypotonia and behavioral abnormalities: An autosomal dominant neurodevelopmental disorder with onset in infancy. IDDHBA is characterized by hypotonia, global developmental delay, learning disability, and behavioral abnormalities, such as autistic features and attention deficit-hyperactivity disorder. Additional variable features may include non-specific facial dysmorphism, congenital heart defects, ocular anomalies, and poor feeding.
