Mutations in the CHAMP1 gene are associated with a neurodevelopmental disorder characterized by intellectual disability and severe speech impairment.[7][8] This condition, often referred to as CHAMP1-related neurodevelopmental disorder, arises from a pathogenic variant in one of the two copies of the gene.[9] The majority of cases result from de novo mutations, meaning they are not inherited from the parents.[10]
Individuals with this disorder typically present with a range of symptoms, including global developmental delay, intellectual disability, and significant speech impairment.[11][12] Common behavioral issues include features consistent with autism spectrum disorder (ASD) and attention-deficit/hyperactivity disorder (ADHD).[13] Other frequently reported conditions include feeding difficulties, vision problems, seizures, and hypotonia (low muscle tone).[11]
Diagnosis is confirmed through genetic testing. Management is supportive and tailored to the individual's symptoms, involving physical, occupational, and speech therapies, as well as educational support.[12]
