Elevated genetic risk for multiple sclerosis emerged in steppe pastoralist populations

"The last 10,000 years have seen some of the most extreme global changes in lifestyle, with the emergence of farming in some regions and pastoralism in others. While 5,000 years ago farmer ancestry predominated across Europe, a relatively diverged genetic ancestry arrived with the steppe migrations around...

Polygenic prediction of educational attainment within and between families from genome-wide association analyses in 3 million

We conduct a genome-wide association study (GWAS) of educational attainment (EA) in a sample of ~3 million individuals and identify 3,952 approximately uncorrelated genome-wide-significant single-nucleotide polymorphisms (SNPs). A genome-wide polygenic predictor, or polygenic index (PGI), explains 12–16%...

Early phase drug trial claims a breakthrough in Huntington disease. IONIS-HTT is an antisense "gene-silencing" compound,

Early phase drug trial claims a breakthrough in Huntington disease. IONIS-HTT is an antisense "gene-silencing" compound, injected in to CSF and designed to reduce the production of all forms of the huntingtin (HTT) protein, which in its mutated variant (mHTT) is responsible for Huntington's Disease....
