Previous studies of X-linked Alport syndrome demonstrated that "severe" COL4A5 mutations (large deletions and rearrangements, nonsense and frame-shift mutations, and glycine substitutions in the carboxy-terminal residues) were associated with early-onset renal failure, hearing loss, and lenticonus in affected male patients. This study examined whether severe mutations also resulted in the typical perimacular dot-and-fleck retinopathy.
