Notable omissions include “Stargardt-like” macular dystrophies caused by ELOVL4 and PROM1 mutations (which have previously been termed STGD3 and STGD4, respectively), as well as other macular dystrophies or CORD caused by mutations in BEST1, MT-TL1 (and other maternally inherited diabetes and deafness (MIDD) genes), RDH12 and CRX, among others [16]. Here, RDH12 is linked to maternally-inherited diabetes and deafness.
