We identified 2 previously described mutations in 4 patients diagnosed with RP (Table 1): a homozygous nonsense mutation (p.Ser542*, HGMD Accession = CM1211361) in an arRP case; and a heterozygous duplication leading to a frameshift (p.Arg872Thrfs*2, HGMD Accession = CI004598), which was identified in three patients diagnosed with adRP (Table 1). This evidence concerns the gene PLIN2 and retinitis pigmentosa 1.
