Project description:Indian rhesus macaque major histocompatibility complex (MHC) variation can influence the outcomes of transplantation and infectious disease studies. Frequently, rhesus macaques are MHC genotyped to identify variants that could account for unexpected results. Since the MHC is only one region in the genome where variation could impact experimental outcomes, strategies for simultaneously profiling variation in the macaque MHC and the remainder of the protein coding genome would be useful. Here we determine MHC class I and class II genotypes using target-capture probes enriched for MHC sequences, a method we term macaque exome sequence (MES) genotyping. For a cohort of 27 Indian rhesus macaques, we describe two methods for obtaining MHC genotypes from MES data and demonstrate that the MHC class I and class II genotyping results obtained with these methods are 98.1% and 98.7% concordant, respectively, with expected MHC genotypes. In contrast, conventional MHC genotyping results obtained by deep sequencing of short multiplex PCR amplicons were only 92.6% concordant with expectations for this cohort.

Project description:Three different experimental approaches were evaluated for discrimination of genomic variance in and between duplicated sequences using 48 markers in duplicon regions and 17 SNPs in unique sequences previously characterized in another study. We found only the method high-throughput single sperm typing could conclusively resolve the alleles of all markers. Resulting data from single sperm analysis were also used to examine the genetic structure of duplicon markers in the human population. Single sperm typing can be a rapid, efficient and accurate method for initial screening and assessment of genetic variation and for detailed genetic analysis of duplicon markers. Keywords: Genotyping

Project description:Younger age and VTE recurrence are more likely to be caused by genetic risk factors than secondary VTE in older patients who more likely have comorbidities. When the exome rare variant genotyping database of the Scripps VTE Registry for adults < 55 yrs old was generated and analyzed for single nucleotide polymorphisms (SNPs). Two F5 related SNPs (rs6025, factor V Leiden and rs6687813) exceeded significance (FDR (false discovery rate) p < 0.05). No other variants met genome-wide significance. When the data for the subgroup of cases with recurrent VTE that are more likely to have genetic risk factors than cases with a single VTE episode were compared to controls (N=211 controls and N=32 recurrent VTE cases), 28 SNPs, including the F5 rs6025 SNP, achieved significance (FDR p < 0.05).

Project description:Histone 3 Lysine 9 (H3K9) methylation is known to be associated with pericentric heterochromatin and important in genomic stability. In this study, we show that trimethylation at H3K9 (H3K9me3) is enriched in an adult neural stem cell niche- the subventricular zone (SVZ) on the walls of the lateral ventricle in both rodent and non-human primate baboon brain. Previous studies have shown that there is significant correlation between baboon and human regarding genomic similarity and brain structure, suggesting that findings in baboon are relevant to human. To understand the function of H3K9me3 in this adult neurogenic niche, we performed genome-wide analyses using ChIP-Seq (chromatin immunoprecipitation and deep-sequencing) and RNA-Seq for in vivo SVZ cells purified from baboon brain. Through integrated analyses of ChIP-Seq and RNA-Seq, we found that H3K9me3-enriched genes associated with cellular maintenance, post-transcriptional and translational modifications, signaling pathways, and DNA replication are expressed, while genes involved in axon/neuron, hepatic stellate cell, or immune-response activation are not expressed. As neurogenesis progresses in the adult SVZ, cell fate restriction is essential to direct proper lineage commitment. Our findings highlight that H3K9me3 repression in undifferentiated SVZ cells is engaged in the maintenance of cell type integrity, implicating a role for H3K9me3 as an epigenetic mechanism to control cell fate transition within this adult germinal niche. SVZ H3K9me3 ChIP-seq profile of an adult baboon subventricular zone was generated by deep sequencing with Illumina HiSeq2000
