A novel G472R mutation in a Turkish family with X-linked Alport syndrome.
Alport syndrome (AS) is a hereditary disorder of progressive nephritis. Most cases are X-linked, but autosomal forms have been reported. The X-linked form is associated with mutations in the COL4A5 gene that encodes the alpha 5 chain of type IV collagen. More than 200 mutations have been reported in X-linked AS. We report a novel 1616 G > A mutation resulting in glycine substitution to arginine at position 472 in a Turkish family with a severely affected man and several variably affected women. This is the first Turkish family in whom the molecular basis of the disease has been reported.
