MPS I – Auditory System

Moderate to severe hearing loss, which correlates with the severity of somatic disease, can occur in patients with MPS I. Hearing loss may be sensorineural or conductive, but is typically mixed^{[1, 2]}. Hearing impairment is most common in the high frequency range and thus can lead to significant difficulties in social interaction.
