摘要

A relationship between the tissue specificity and the evolutionary origin, or lineage, of genes has been shown previously. Here, a more systematic statistical analysis of human genes shows that tissue specific genes tend to be of relatively recent evolutionary origin. While there is no agreed definition of the lineage of a gene, we use two methods to define this concept. The first relies on the presence or not of orthologs in the human and mouse genomes to define relatively old or new genes. The second utilizes the ortholog species group of the gene to compute a lineage index based on the evolutionary distance of those species from humans. Both definitions show similar results. Although the amount of available data is not enough for statistically sound conclusions, a relationship between intrinsically disordered proteins and the lineage of the corresponding genes was found suggesting further study.
