Project description:There is growing evidence that genomic DNA sequence changes occur in individual somatic cells during the lifetime of an individual and accumulation of these changes may influence aging and disease. In light of this, and contradicting reports regarding discordant copy number profiles between MZ twins(BARANZINI et al. 2010; BRUDER et al. 2008), we set out to identify de novo somatic copy number mutations in DNA from blood for MZ twin pairs of Mexican American descent who were participants of the San Antonio Family Heart Study (SAFHS) or San Antonio Family Diabetes/Gallbladder study (SAFDGS). By applying circular binary segmentation (CBS) to B-allele ratio differences we determined that the 3 MZ twin pairs in this study had concordant copy number profiles. We also detected 2 de novo germ-line CNVs in 2 MZ twin pairs from the SAFHS.

Project description:Accurate description of a microbial community is an important first step in understanding the role of its components in ecosystem function. A method for surveying microbial communities termed Serial Analysis of Ribosomal DNA (SARD) is described here. Through a series of molecular cloning steps, short DNA sequence tags are recovered from the fifth variable (V5) region of the prokaryotic 16S rRNA gene from microbial communities. These tags are ligated to form concatemers comprised of 20-40 tags which are cloned and identified by DNA sequencing. Four agricultural soil samples were profiled with SARD to assess the method’s utility. A total of 37,008 SARD tags comprising 3,127 unique sequences were identified. Comparison of duplicate profiles from one soil genomic DNA preparation revealed the method was highly reproducible. The large numbers of singleton tags together with non-parametric richness estimates indicated a significant amount of sequence tag diversity remained undetected with this level of sampling. The abundance classes of the observed tags were scale-free and conformed to a power law distribution. Numerically, the majority of the total tags observed belonged to abundance classes that were each present at less than 1% of the community. Over 99% of the unique tags individually made up less than 1% of the community. Therefore, from either numerical or diversity standpoints, low abundant taxa comprised a significant proportion of the microbial communities examined and could potentially make a large contribution to ecosystem function. SARD may provide a means to explore the ecological role of these rare members of microbial communities in qualitative and quantitative terms.
