The inherited pattern of patients with a genetic disease was autosomal dominant (138, 29.9%), autosomal recessive (251, 54.5%), X-linked (42, 9.1%), mitochondrial (29, 6.3%), and one patient had a multimendelian phenotype of syndromic RP due to mutations in the USH2A gene with recessive inheritance and the RHO gene which is autosomal dominant. This evidence concerns the gene RHO and retinitis pigmentosa 1.
