Project description:Structural variation has played an important role in the evolutionary restructuring of human and great ape genomes. We generated approximately 10-fold genomic sequence coverage from a western lowland gorilla and integrated these data into a physical and cytogenetic framework to develop a comprehensive view of structural variation. We discovered and validated over 7,665 structural changes within the gorilla lineage including sequence resolution of inversions, deletions, duplications and retrotranspositions. A comparison with human and other ape genomes shows that the gorilla genome has been subjected to the highest rate of segmental duplication. We show that both the gorilla and chimpanzee genomes have experienced independent yet parallel patterns of structural mutation that have not occurred in humans, including the formation of subtelomeric heterochromatic caps, the hyperexpansion of segmental duplications and bursts of retroviral integrations. Our analysis suggests that the chimpanzee and gorilla genomes are structurally more derived than either orangutan or human. all combinations of human, chimpanzee and gorilla are used in 2 different arrayCGH designs. First, a standard 2.1 was used to detected CNVs, and second, we used a custom designed arrayCGH to validate gorilla specific duplications and deletions

Project description:Copy number variants (CNVs) are heritable gains and losses of genomic DNA in normal individuals. While copy number variation is widely studied in humans, our knowledge of CNVs in other mammalian species is more limited. We have designed a custom array-based comparative genomic hybridization (aCGH) platform with 385,000 oligonucleotide probes based on the reference genome sequence of the rhesus macaque (Macaca mulatta), the most widely studied non-human primate in biomedical research. We used this platform to identify 123 CNVs among 10 unrelated macaque individuals, with 24% of the CNVs observed in multiple individuals. We found that segmental duplications were significantly enriched at macaque CNV loci. We also observed significant overlap between rhesus macaque and human CNVs, suggesting that certain genomic regions are prone to recurrent CNV formation and instability, even across a total of ~50 million years of primate evolution (~25 million years in each lineage). Furthermore, for 8 of the CNVs that were observed in both humans and macaques, previous human studies have reported a relationship between copy number and gene expression or disease susceptibility. Therefore, the rhesus macaque offers an intriguing, non-human primate model organism for which hypotheses concerning the specific functions of phenotypically-relevant human CNVs can be tested.

Project description:This study centered on using a custom made Nimblegen aCGH chip that targeted all segmental duplications in the canine genome to identify associated CNVs. A total of 19 hybridizations were performed in a panel of diverse dogs and a single wolf. Using computational approaches all segmental duplications were identified in the canFam2 genome of the dog. A custom aCGH chip was then built that densely interrogated these segmental duplications for CNVs in a panel of diverse dog breeds and a single wolf.
