For example, a stop-gain variant (NM_001292009:c.C8608T:p.R2870X) in EYS, a common gene for retinitis pigmentosa in autosomal recessive mode, was detected in one homozygous macaque and in 20 heterozygous macaques (Supplementary Fig. 3c). The gene discussed is EYS; the disease is retinitis pigmentosa.
