Symbol : CNA2;
CISMeF acronym : CNA2;
Type : Phenotype, molecular basis known;
Description : Cornea plana is clinically characterized by reduced corneal curvature leading in most
cases to hyperopia, hazy corneal limbus, and arcus lipoides at an early age. An autosomal
dominant form (CNA1; 121400) is mild, whereas an autosomal recessive form (CNA2) is
severe and frequently associated with additional ocular manifestations (Tahvanainen
et al., 1996).;
