    Genomic studies of Heliconius butterflies provide evidence that Heliconius elevatus is a hybrid species, and that its speciation was driven by introgression of traits from Heliconius melpomene into the other parent, an ancestor of Heliconius pardalinus.

    The Pharma Proteomics Project generates the largest open-access plasma proteomics dataset to date, offering insights into trans protein quantitative trait loci across multiple biological domains, and highlighting genetic influences on ligand–receptor interactions and pathway perturbations across a diverse collection of cytokines and complement networks.

    To understand the contribution of variants to transcript expression regulation, long-read transcriptome data are generated from the GTEx resource, and a new software package to perform allele-specific analysis is developed.

    cis-RNA editing quantitative trait loci, which are associated with immunogenic double-stranded RNAs, underlie genome-wide association study variants in common autoimmune and inflammatory diseases.

    An analysis of 16 health-related quantitative traits in approximately 350,000 individuals reveals statistically significant associations between genome-wide homozygosity and four complex traits (height, lung function, cognitive ability and educational attainment); in each case increased homozygosity associates with a decreased trait value, but no evidence was seen of an influence on blood pressure, cholesterol, or ten other cardio-metabolic traits.

    Obesity-associated noncoding sequences within FTO are functionally connected with IRX3, and long-range enhancers in this region recapitulate aspects of IRX3 expression, suggesting that the obesity-associated interval is part of IRX3 regulation; Irx3-deficient mice have lower body weight and are resistant to diet-induced obesity, suggesting IRX3 as a novel determinant of body mass and composition.

    In a cross between two yeast strains, detected loci are found to explain nearly the entire additive contribution to heritable variation for a number of quantitative traits.

    A gene that is present in phosphate-deficiency-tolerant rice but absent from modern rice varieties is characterized and named phosphorus-starvation tolerance 1 (PSTOL1); overexpression of PSTOL1 in rice species that naturally lack this gene confers tolerance to low phosphorus conditions, a finding that may have implications for agricultural productivity in rice-growing countries.

    In human lymphoblastoid cell lines, 8,902 loci were identified at which genetic variation is significantly associated with local DNase I sensitivity; these variants are responsible for a large fraction of expression quantitative trait loci.

    This very large genome-wide association study identifies hundreds of new genetic variants influencing adult height in at least 180 loci enriched for genes involved in skeletal growth defects. The results show that the likely causal gene is often located near the most strongly associated variant, that many loci have multiple independently associated variants and that associated variants are enriched for likely functional effects on genes.

    The genetic basis of common traits may be buried deeper than researchers had thought.

    Complex heritable traits — such as human height and many human diseases — are caused by multiple genetic loci, each with small effects. It is hard to identify such loci, however, because of a lack of statistical power. Now, a method has been developed to overcome this problem. The method has been applied to chemical resistance traits and mitochondrial function in yeast, and has identified loci for each of these phenotypes.

    There is much interest in understanding the genetic mechanisms that underlie individual variations in gene expression. Here, RNA sequencing has been used to study gene expression in lymphoblastoid cell lines derived from Nigerian individuals for whom extensive genotype information is known. Numerous genetic determinants of variation in gene expression were identified, including variation in transcription, splicing and allele-specific expression.

    Here, sequencing has been used to characterize the mRNA fraction of the transcriptome in Caucasian individuals, to provide a fine-scale view of transcriptomes and to identify genetic variants that affect alternative splicing. Measuring allele-specific expression identified rare expression quantitative trait loci (eQTLs) and allelic differences in transcript structure, revealing new properties of genetic effects on the transcriptome.
