Three genome-wide association studies of prostate cancer deliver a mix of newly identified associations, tripling the available number of candidate genes, biomarkers and variants potentially useful in risk prediction.
Rare syndromes offer unique opportunities to gain insight into central physiological processes. By deciphering the genetic basis of two rare inherited diseases, two studies identify a key role for P2Y5, a G protein–coupled receptor, in hair follicle development.
During meiosis, crossovers are regulated such that each pair of chromosomes has at least one crossover and multiple crossovers are evenly spaced. A new study leads to surprising insights regarding the timing of crossover regulation through the analysis of two genes involved in synaptonemal complex elongation.
Cranial neural crest cell migration is a prerequisite for normal craniofacial morphogenesis in animals. A new study shows that the movement of a specific subset of cranial neural crest cells is exquisitely sensitive to concentrations of a microRNA that targets platelet-derived growth factor receptor alpha mRNA.
A new mapping study identifies a natural protein variant influencing oil content and composition in maize seeds. This example illustrates the power of exploiting natural variation to improve crop yields and address current breeding challenges.
