Findings could lead to gene therapy cure for childhood blindness

In findings that could lead to curing some forms of congenital blindness through gene therapy, researchers at UCLA have discovered that RPE65, a gene missing in infants born with the blinding disease Leber congenital amaurosis, is also a key enzyme in the visual cycle. The identity of this enzyme has long been a mystery to scientists.

New clues to amyloidoses

Familial amyloid polyneuropathy (FAP), a hereditary disease characterised by abnormal deposits of insoluble protein in the organs, results from a mutation in a single gene (the transthyretin or TTR gene). Nevertheless, disease incidence and age of onset can vary significantly between patients what have always puzzled scientists.
