16S rRNA gene sequencing and healthy reference ranges for 28 clinically relevant microbial taxa from the human gut microbiome.

Project description:Changes in the relative abundances of many intestinal microorganisms, both those that naturally occur in the human gut microbiome and those that are considered pathogens, have been associated with a range of diseases. To more accurately diagnose health conditions, medical practitioners could benefit from a molecular, culture-independent assay for the quantification of these microorganisms in the context of a healthy reference range. Here we present the targeted sequencing of the microbial 16S rRNA gene of clinically relevant gut microorganisms as a method to provide a gut screening test that could assist in the clinical diagnosis of certain health conditions. We evaluated the possibility of detecting 46 clinical prokaryotic targets in the human gut, 28 of which could be identified with high precision and sensitivity by a bioinformatics pipeline that includes sequence analysis and taxonomic annotation. These targets included 20 commensal, 3 beneficial (probiotic), and 5 pathogenic intestinal microbial taxa. Using stool microbiome samples from a cohort of 897 healthy individuals, we established a reference range defining clinically relevant relative levels for each of the 28 targets. Our assay quantifies 28 targets in the context of a healthy reference range and correctly reflected 38/38 verification samples of real and synthetic stool material containing known gut pathogens. Thus, we have established a method to determine microbiome composition with a focus on clinically relevant taxa, which has the potential to contribute to patient diagnosis, treatment, and monitoring. More broadly, our method can facilitate epidemiological studies of the microbiome as it relates to overall human health and disease.

Advancing a Clinically Relevant Perspective of the Clonal Nature of Cancer

Project description:We used DNA content-based flow cytometry to distinguish and isolate nuclei from clonal populations in primary tissues from three disparate cancers with variable clinical histories. We then developed a methodology to adapt flow cytometrically purified nuclei samples for use with whole genome technologies including aCGH and next generation sequencing (NGS). Our results demonstrate that selected aberrations in the genomes of distinct clonal populations in each patient create clinically relevant contexts at least with respect to the cancer types profiled in this study.

Clinically Relevant Copy Number Variations Detected in Cerebral Palsy

Project description:Cerebral palsy (CP) represents a group of non-progressive clinically heterogeneous disorders that are characterized by motor impairment and early age-of-onset, frequently accompanied by co-morbidities. The cause of CP has historically been attributed to environmental stressors resulting in brain damage. While genetic risk factors are also implicated, guidelines for diagnostic assessment of CP do not recommend for routine genetic testing. Given numerous reports of etiologic copy number variations (CNVs) in other neurodevelopmental disorders, we used microarrays to genotype a population-based prospective cohort of children with CP and their parents. Here we identify de novo CNVs in 8/115 (7.0%) CP patients (~1% rate in controls). In four children, large chromosomal abnormalities deemed pathogenic were found, and they were significantly more likely to have severe neuro-motor impairments than those CP subjects without such alterations. Overall the CNV data would have impacted our diagnosis or classification of CP in 11/115 (9.6%) families.

Clinically Relevant Copy Number Variations Detected in Cerebral Palsy. Nature Communications, 2015. Following our rigorous quality control procedure, we successfully genotyped 147 proband samples from individuals with cerebral palsy (81 males and 66 females) and 282 samples obtained from parents (134 males and 148 females). This facilitated the identification of de novo and rare inherited copy number variations of clinical interest.
