Knobloch syndrome 1 (KNO1; MIM 267750) is an autosomal recessive developmental disorder caused by mutations in the COL18A1 gene. It is characterized by eye abnormalities and occipital skull defects. The characteristic eye findings include high myopia, vitreoretinal degeneration, retinal detachment, cataract and lens dislocation. The occipital skull defects range from occult cutis aplasia to occipital encephalocele.read more
