Rare diseases: what are they and who do they affect?

A Rare Disease is one with a prevalence of less than 1 case per 2000 inhabitants. It is estimated that there are between 5,000 and 7,000 different rare diseases, some of which affect a small number of people around the world. However, taking into account the different pathologies, it is calculated that between 6 and 8% of the world population would be afflicted by any of these diseases. Therefore, an estimated 30 million Europeans suffer from various rare diseases.

In the laboratory we are interested in understanding the mechanisms subjacent to Townes-Brocks Syndrome ad other diseases related to the Ubiquitin-like family, i.e. Angelman Syndrome.

Spalt-like (SALL) Family of Transcription Factors

Mutations in this important family of zinc finger transcription factors are related to hereditary syndromes, such as the Townes-Brocks or the Okihiro (Duane-Radial Ray) Syndromes. These are considered as Rare Diseases and characterized by hearing loss, renal and limb malformations, among other symptoms.

In Drosophila we studied the role of Sall factors in neurodegeneration, limb and nervous system formation. We also studied the modification of these proteins by SUMO and how this affects their role.

In humans and mouse models we study the mechanis by which these factors are involved in Townes-Brocks Syndrome. We discovered that primary cilia are altered in cells from affected individuals.
