Regarding the two remaining deletions, the one described by Akilapa et al. in 2015 lies in 12q21.31q21.32 region and does not overlap with the CR [9], whereas the smallest 1.3 Mb deletion, including the four DCN, KERA, LUM and EPYC genes, defines the contiguous gene deletion syndrome PACD (posterior amorphous corneal dystrophy; OMIM 612868) [10]. Here, KERA is linked to posterior amorphous corneal dystrophy.
