Furthermore, 24 families had VUS, two families with variants in genes related to non-syndromic EoHM (SCO2 and ZNF644) and seven families with variants in genes associated with other retinal dystrophies (TRPM1, CACNA1F, KCNV2, RDH5 and MERTK). This evidence concerns the gene SCO2 and Retinal dystrophy.
