[i] The genes that are not available means the mRNA sequences are not offered by the Consortium. The genes with 1 or 2 exons include 42 (or 341) functional genes and 56 (or 141) pseudogenes (processed or nonfunctional pseudogenes) on Chromosome 21 (or 22). The EST match only means the matched EST fragments are not open or the translated sequences <50 amino acids. The 1302 (or 3001) exons of Chromosome 21 (or 22) annotated by CRASA include 1145 (or 2556) exons both of whose boundaries are correctly matched and 157 (or 445) exons that are only partially matched to the actual exons.
