Vissers-Bodmer syndrome

Summary

Vissers-Bodmer syndrome (VIBOS) is characterized by global developmental delay with variably impaired intellectual development, speech delay, motor delay, and behavioral abnormalities apparent from infancy. The phenotype is highly variable: some individuals have only mild learning difficulties, whereas others have severe cognitive impairment with IQ in the 50s. Many patients have behavioral abnormalities, including autism spectrum disorder, ADD, ADHD, obsessive-compulsive disorder, and impulsivity. Other common features include growth impairment abnormalities, hypotonia, and distal skeletal defects, such as foot and hand deformities. Less common features include seizures, brain abnormalities on MRI, feeding problems, and joint hypermobility. Most individuals have dysmorphic facial features, but there is no recognizable gestalt (summary by Vissers et al., 2020). [from OMIM]
