*2.13. ABCA2*

The ABCA2-202 transcript is 8103 bp long and contains 49 exons. The 5′UTR is 97 bp long. The most conserved sub-region was localized to −65 to −12. One uATG (−88) is conserved within primates and rodents (cat. 2); it has an adequate context, however, a low TIS score. Prediction programs found one probable 66 nt long uORF starting at the uATG and one RG4-forming sequence (−81 to −34). Two stem loops were described within this region. The ABCA2 protein was found to be expressed in almost all human tissues lacking only in adipose tissue (44 out of 45). The mode expression score was medium, enhanced only in brain.
