Genetic Sharing with Cardiovascular Disease Risk Factors and Diabetes Reveals Novel Bone Mineral Density Loci.

Bone Mineral Density (BMD) is a highly heritable trait, but genome-wide association studies have identified few genetic risk factors. Epidemiological studies suggest associations between BMD and several traits and diseases, but the nature of the suggestive comorbidity is still unknown. We used a novel genetic pleiotropy-informed conditional False Discovery Rate (FDR) method to identify single nucleotide polymorphisms (SNPs) associated with BMD by leveraging cardiovascular disease (CVD) associated disorders and metabolic traits. By conditioning on SNPs associated with the CVD-related phenotypes, type 1 diabetes, type 2 diabetes, systolic blood pressure, diastolic blood pressure, high density lipoprotein, low density lipoprotein, triglycerides and waist hip ratio, we identified 65 novel independent BMD loci (26 with femoral neck BMD and 47 with lumbar spine BMD) at conditional FDR < 0.01. Many of the loci were confirmed in genetic expression studies. Genes validated at the mRNA levels were characteristic for the osteoblast/osteocyte lineage, Wnt signaling pathway and bone metabolism. The results provide new insight into genetic mechanisms of variability in BMD, and a better understanding of the genetic underpinnings of clinical comorbidity

Righting rewritings of the myth of Mentor: A critical perspective on career guidance mentoring

Mentoring is entering the repertoire of career guidance techniques as careers services prioritise socially excluded young people. This article explores the use of Homer's Odyssey as a source of definitions and legitimations of many current accounts of mentoring. Contrasting modern versions of Homer's myth of Mentor with the original, it draws on feminist and class perspectives to question the basis on which such myths are used to proclaim the origins of a very contemporary phenomenon. It identifies an emerging discourse of mentoring, a régime of truth which exerts control not only over the young people being mentored, but also over career guidance staff expected to act as mentors in new Personal Adviser roles
