*2.4. ABCA4*

The transcript ABCA4-201 is 7328 bp long and has 50 exons. The 5′UTR is 103 bp long. The sub-region −65 to −50 was determined to be the most conserved. One uATG (−62) is conserved in placental mammals (cat. 3); however, it has a weak context and low TIS score. No probable uORF or RG4-forming sequence was detected. Two stem loops were predicted to this region. The ABCA4 protein was found to be expressed only in the retina with a high score.
