Summary

Microphthalmia designates a heterogeneous group of ocular malformations with a more or less evident reduction in the size of the eyeball. Additional features include high hypermetropia and a short axial length. The size of the anterior chamber and the cornea may also be reduced, whereas the lens is normal or thicker than usual for age (summary by Fuchs et al., 2005). Genetic Heterogeneity of Isolated Microphthalmia MCOP2 (610093) is caused by mutation in the CHX10 gene (142993) on chromosome 14q24. MCOP3 (611038) is caused by mutation in the RAX gene (601881) on chromosome 18q21.3. MCOP4 (613094) is caused by mutation in the GDF6 gene (601147) on chromosome 8q22.1. MCOP5 (611040) is caused by mutation in the MFRP gene (606227) on chromosome 11q23. MCOP6 (613517) is caused by mutation in the PRSS56 gene (613858) on chromosome 2q37.1. MCOP7 (613704) is caused by mutation in the GDF3 gene (606522) on chromosome 12p13.1. MCOP8 (615113) is caused by mutation in the ALDH1A3 gene (600463) on chromosome 15q26. [from OMIM]
