The sequencing of the human genome and the genomes of closely related primates has revealed the presence of a small number of human- or human-lineage-specific genes that have no orthologs in lower species. Human-specific and human-lineage-specific genes are likely to function as regulators of cell signaling events, and by fine-tuning pathways, the encoded proteins may contribute to human-specific characteristics and behaviors. In addition, human-specific genes may represent biomarkers for examining human-specific characteristics of various diseases. Investigation of the gene encoding TBC1D3 is one example of a search that may lead to understanding the evolution and the function of human-specific genes, because it is absent in lower species and present in high copy number in the human genome.&lt;/p&gt;
