Development and performance of a comprehensive targeted sequencing assay for pan-ethnic screening of carrier status
J Mol Diagn. 2014 Feb 10. [Epub ahead of print]
Tanner, et al.

The authors report the development of the Pan-Ethnic Carrier Screening assay, a targeted sequencing assay for routine screening that simultaneously detects 461 common mutations in 91 different genes underlying severe, early-onset monogenic disorders. The assay is based on the Affymetrix GeneChip microarray platform but generates genomic DNA sequence as the output.

Multilayer-omics analysis of renal cell carcinoma, including the whole exome, methylome and transcriptome.
Int J Cancer. 2014 Feb 6. [Epub ahead of print]
Arai E, et al.

The aim of this study was to identify pathways that have a significant impact during renal carcinogenesis. Sixty-seven paired samples of both non-cancerous renal cortex tissue and cancerous tissue from patients with clear cell renal cell carcinomas were subjected to whole-exome, methylome, and transcriptome analyses using Agilent SureSelect All Exon capture followed by sequencing on an Illumina HiSeq 2000 platform, as well as further analysis by Infinium HumanMethylation27 BeadArray and Agilent SurePrint Human Gene Expression microarray. Sanger sequencing and quantitative reverse transcription-PCR were performed for technical verification.

High-resolution microarray in the assessment of fetal anomalies detected by ultrasound.
Aust N Z J Obstet Gynaecol. 2014 Feb;54(1):46-52.
Charan P, et al.

A prospective cross-sectional study was conducted on women diagnosed with a fetal anomalies between February 2009 and December 2011 who were offered testing by microarray analysis and fluorescent in situ hybridization instead of standard karyotyping. The authors determined that 11.8 percent of the cases would have had a genetic basis of an abnormality with a FISH and banded karyotype, while that figure was approximately tripled to 28.8 percent when they offered both FISH and microarray.

Y Chromosome Study Reveals Details on Timing of Human Settlement in Americas

A Y chromosome-based analysis suggests South America may have first been settled more than 18,000 years ago, according to a new PLOS One study.

New Insights Into TP53-Driven Cancer

Researchers examine in Nature how TP53 mutations arise and spark tumor development.

Mapping Single-Cell Genomic, Transcriptomic Landscapes of Colorectal Cancer

In Genome Medicine, researchers present a map of single-cell genomic and transcriptomic landscapes of primary and metastatic colorectal cancer.

Expanded Genetic Testing Uncovers Hereditary Cancer Risk in Significant Subset of Cancer Patients

In Genome Medicine, researchers found pathogenic or likely pathogenic hereditary cancer risk variants in close to 17 percent of the 17,523 patients profiled with expanded germline genetic testing.
