Biochemical and biophysical research communications, 2012•ElsevierMutations in the cone–rod homeobox gene (CRX) are associated with cone–rod dystrophy
(CORD), Leber congenital amaurosis (LCA), and, in rare cases, retinitis pigmentosa (RP). In
this study, three variations were detected in 3 of 130 families with CORD, including two
novel mutations, c. 239A> G (p. Glu80Gly) and c. 362C> T (p. Ala121Val). So far, 49
mutations in CRX were reported, affecting about 2.35% of LCA, 4.76% of CORD, and 0.80%
of RP. These mutations can be classified as missense (38.78%), nonsense (4.08%), deletion …

These mutations can be classified as missense (38.78%), nonsense (4.08%), deletion (36.73%), insertion (16.33%), and indel (4.08%). They distributed in the three coding exons without mutation hot spots. No clear genotype–phenotype correlation could be established so far.
