Natural history study of Stargardt’s disease to include very rare forms of the condition

Organisers behind the ProgStar Study, a natural history study of the course of Stargardt’s disease, have announced that it will now include patients carrying a very rare autosomal dominant form of the disease, forms arising from mutations in the PROM1 gene responsible for Stargardt disease type 4 (STGD4). The disease population for STGD4 is estimated to be extremely rare with only 41 individuals reported worldwide in the scientific literature to date.
