Question

Quizplus · Accepted Answer

The syndrome described in the question, with hearing loss and retinitis pigmentosa, is characteristic of Usher syndrome. Asperger syndrome is a developmental disorder associated with impairments in social interaction and communication skills. Down syndrome is a genetic disorder characterized by intellectual disability and physical features such as a flattened face and short stature. CHARGE syndrome is a genetic disorder that can affect multiple organs, including the eyes, ears, and heart. However, it typically does not result in deaf-blindness, and retinitis pigmentosa is not a diagnostic feature of this syndrome.
