[i] The size of the loci in base pairs, the % repeats, the number of amino acids (aa), and the total size of exons and introns are shown for eight mammalian species. These numbers are estimates due to sequence gaps in some species.

[ii] ^aSpecified exons or introns available for analysis.

[iii] ^bExon 1 (171 bp) identified using BLAT with a human exon 1 sequence and intron size estimated based on the position of exon 1.
