About us

Famiglie GNAO1 Association was established in 2019 by a group of families in Italy to better support other families in Italy afflicted by the GNAO1 disorder. Whilst focused on serving the patient community within Italy, we aim to collaborate with patient family groups, physicians and researchers in other countries to facilitate information sharing and ultimately to find a cure for this rare disease.

Rare disease

In Europe a disease is classified as rare if it affects fewer than 1 in 2000 people. These diseases are rare but numerous, estimated to affect 3%-5% of the global population. There are currently over 7000 known rare diseases, and new ones are described in scientific publications every year. 80% of rare diseases are of genetic origin and emerge during childhood. It is estimated that in Italy there are 2 million rare disease patients and 30 million in Europe.

In recent years, an increasing number of research groups and clinicians have focused their attention on this pathology, to try to shed light both on the neurological mechanisms that underlie it, and on its manifestation and evolution. This section collects works from the international scientific community, which is certainly an important resource for anyone who can deepen their knowledge of the disease.
