Mutations and novel unclassified variants are presented. The asterisk indicates that this has been previously reported elsewhere as a pathologic mutation. The sequence variations without the asterisk are novel ones with further analyses supporting or excluding pathogenicity including frequency in normal control, amino acid conservation and in-silico prediction using softwares. We classified H631P in RPGRIP1 and G333D in CRB1 among five missense variants as pathogenic mutations, but other missense ones as unclassified variants.
