Autosomal dominant nanophthalmos is characterized by a small eye, as indicated by short axial length, high hyperopia, high lens/eye volume ratio, and a high incidence of angle-closure glaucoma (summary by Othman et al., 1998).
Genetic Heterogeneity of Nanophthalmos
Nanophthalmos-1 (NNO1) has been mapped to chromosome 11p. Nanophthalmos-2 (NNO2; 609549) is caused by mutation in the MFRP gene (606227) on chromosome 11q23. Nanophthalmos-3 (NNO3; 611897) has been mapped to chromosome 2q11-q14. Nanophthalmos-4 (NNO4; 615972) is caused by mutation in the TMEM98 gene (615949) on chromosome 17q11. [from
