Summaries for Intellectual Developmental Disorder with Behavioral Abnormalities...

OMIM : 56 Patients with intellectual developmental disorder with behavioral abnormalities and craniofacial dysmorphism with or without seizures (IDDBCS) have impaired intellectual development or developmental delay of varying severity with impaired motor skills and language delay. Macrocephaly, obesity, and overgrowth are frequently seen. Approximately half of patients experience seizures, and neurobehavioral disorders including autism are usually present (Hamanaka et al., 2019; Kim et al., 2019). (618725)

MalaCards based summary : Intellectual Developmental Disorder with Behavioral Abnormalities and Craniofacial Dysmorphism with or Without Seizures, is also known as neurodevelopmental disorder with macrocephaly and with or without seizures. An important gene associated with Intellectual Developmental Disorder with Behavioral Abnormalities and Craniofacial Dysmorphism with or Without Seizures is PHF21A (PHD Finger Protein 21A).

UniProtKB/Swiss-Prot : 73 Neurodevelopmental disorder with macrocephaly and with or without seizures: An autosomal dominant neurodevelopmental disorder characterized by impaired intellectual development, developmental delay of varying severity, impaired motor skills and language delay. Additional clinical features include macrocephaly, obesity, overgrowth, craniofacial dysmorphism, epilepsy, and variable behavioral manifestations including autism and attention deficit hyperactivity disorder.
