Hypomorphic IDUA genotypes are associated with retinitis pigmentosa in individuals without syndromic mucopolysaccharidosis type I.
Bi-allelic variants in IDUA classically cause mucopolysaccharidosis type I (MPS I), a multisystem lysosomal storage disorder. This study describes 14 individuals from 12 families presenting with retinitis pigmentosa, later attributed to bi-allelic IDUA genotypes. Notably, seven individuals, despite comprehensive system...
