Type 5 has been mapped to the human chromosome 4q24, which is a novel locus for nonsyndromic OCA (Kamaraj et al., 2014; Visser, Kayser, Grosveld, & Palstra, 2014), and type 6 and type 7 are respectively caused by mutations in SLC24A5 and C10orf11 (Wei et al., 2013). This evidence concerns the gene LRMDA and oculocutaneous albinism.
