the alpha-mannosidosis enzyme.

If you, or anyone you know, is or may be affected with symptoms of alpha-mannosidosis, please speak to a healthcare professional as soon as possible to get appropriate advice.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Further support and resources<\/h3>\n\n\n\n<p>There are several organisations and charities across the UK and Ireland that aim to raise awareness for patients with rare diseases.
