This is illustrated by the finding that the 15K retinome which comprises 15,645 transcripts including those which were solely found in a single study (Table 2), contains an additional five of the 102 known retinal disease genes (RHOK, MTATP6, CHM, LRAT, RIMS1) not included in the 13K retinome. Here, CHM is linked to Abnormal retinal morphology.
