SLC40A1 and hereditary hyperferritinemia with congenital cataracts: These include hereditary hyperferritinemia cataract syndrome (HHCS) due to mutations in the IRE region of FTL, so-called benign hyperferritinemia due to mutations in the first exon of FTL, and ferroportin disease due to loss-of-function mutations of SLC40A1 [24,62,63].
