Cohen syndrome (COH1; MIM 216550) is an autosomal recessive developmental disorder caused by mutations in the VPS13B gene. It affects multiple organ systems. It is characterized predominantly by postnatal microcephaly, intellectual disability, facial dysmorphism, pigmentary retinopathy, myopia, and intermittent neutropenia. Additional findings may include obesity, mitral valve prolapse, hypotonia, and joint hypermobility.
