Beta-Mannosidosis

Beta-mannosidosis is a very rare inherited condition in which the enzyme beta-mannosidase is missing or not working, so sugar-containing molecules build up inside cells. Features vary widely and can include intellectual disability, developmental delay, hearing loss, speech difficulties and recurrent infections. There is no specific treatment, so care focuses on supporting development, hearing, speech and general health.

This overview is general information, not an individual medical assessment. Research is selected automatically and may include mismatches. How we select and explain research.

Beta-Mannosidosis is very rare and little research has been published, so this page includes research from every year, including case reports about individual patients. Case reports are marked, and describe one person's experience rather than tested results.
