Apart from the 15 highlighted genes described above, mutations of ARL3, KIZ, RP9, and RPGR were involved in retinitis pigmentosa [70,71,72,73], LEMD2 and DNMBP were involved in juvenile cataracts or infantile cataracts [74,75], and POLG2 was involved in progressive external ophthalmoplegia [76]. The gene discussed is LEMD2; the disease is progressive external ophthalmoplegia.
