LRRC37 family phylogeny. Maximum likelihood phylogenetic trees were constructed using noncoding regions from intron 1 (left) and intron 8 (right). Trees are drawn to scale, with branch lengths measured in the number of substitutions per site and bootstrap values (1000 replicates) shown. Human and orangutan A- and B-type copies are shaded blue and yellow, respectively; the monophyletic clade of HSA-F paralogs is gray shaded; branches with HSA-C, HSA-D, PPY8, MMU5, and MMU6 orthologous copies are shaded green. Copies clearly mapping to syntenic locations are signed by a superscript.
