Genome-wide analysis of 102,084 migraine cases identifies 123 risk loci and subtype-specific risk alleles
Migraine affects over a billion individuals worldwide but its genetic underpinning remains largely unknown. Here, we performed a genome-wide association study of 102,084 migraine cases and 771,257 controls and identified 123 loci, of which 86 are previously unknown. These loci provide an opportunity to evaluate shared and distinct genetic components in the two main migraine subtypes: migraine with aura and migraine without aura. Stratification of the risk loci using 29,679 cases with subtype information indicated three risk variants that seem specific for migraine with aura (in HMOX2, CACNA1A and MPPED2), two that seem specific for migraine without aura (near SPINK2 and near FECH) and nine that increase susceptibility for migraine regardless of subtype. The new risk loci include genes encoding recent migraine-specific drug targets, namely calcitonin gene-related peptide (CALCA/CALCB) and serotonin 1F receptor (HTR1F). Overall, genomic annotations among migraine-associated variants were enriched in both vascular and central nervous system tissue/cell types, supporting unequivocally that neurovascular mechanisms underlie migraine pathophysiology.publishedVersionPeer reviewe

Prospects for Galactic and stellar astrophysics with asteroseismology of giant stars in the TESS continuous viewing zones and beyond
The NASA- mission presents a treasure trove for understanding the
stars it observes and the Milky Way, in which they reside. We present a first
look at the prospects for Galactic and stellar astrophysics by performing
initial asteroseismic analyses of bright () red giant stars in the
Southern Continuous Viewing Zone (SCVZ). Using three independent
pipelines, we detect and in 41% of the 15,405
star parent sample (6,388 stars), with consistency at a level of in
and in . Based on this, we predict
that seismology will be attainable for giants across the
whole sky, subject to improvements in analysis and data reduction techniques.
The best quality -CVZ data, for 5,574 stars where pipelines returned
consistent results, provide high quality power spectra across a number of
stellar evolutionary states. This makes possible studies of, for example, the
Asymptotic Giant Branch bump (AGBb). We demonstrate that mixed modes
and rotational splitting are cleanly observed in the 1-year data set. By
combining -CVZ data with -HERMES, ,
APOGEE and we demonstrate the potential for Galactic archaeology
studies using the data, which provides good age precision and accuracy that
reproduces the age of high stars and relationships
between mass and kinematics from studies based on . Better quality
astrometry and simpler target selection than the sample makes
this data ideal for studies of the local star formation history and evolution
of the Galactic disc. These results provide a strong case for detailed
spectroscopic follow-up in the CVZs to complement that which has been (or will
be) collected by current surveys. [Abridged]Comment: 15 Pages (+6 Pages Appendices), 14 Figures (+3 in Appendices).
