Table 5. Amino acid substitutions detected in the CRB2 gene
Eleven amino acid subsitutions were identified by mutation analysis of 85 RP patients and 79 LCA patients. The frequency of these substitutions was analyzed in control individuals. In addition, we determined whether these amino acid changes are conservative or nonconservative with respect to charge, size, and polarity, the likelihood that the amino acids are replaced during evolution (Blosum62 score), and whether they are conserved in homologous domains of Crumbs, CRB1 and CRB2. Numbering is based on GenBank entry AY720432.
