    missense   abnormal protein/loss of function missense codon 373 in autosomal recessive form
    other   abnormal protein/loss of function missense A669T substitution in autosomal dominant form
    insertion   unknown  
    deletion   under-expression nonsense-mediated mRNA decay (NMD)-sensitive mutation
    Remark(s) RP1 compound heterozygous nonsense mutations in a Chinese pedigree leads to autosomal recessive retinitis pigmentosa
