A new senior editor is joining GENETICS in the Statistical Genetics and Genomics section. We’re excited to welcome Hongyu Zhao to the editorial team. Hongyu ZhaoSenior Editor Hongyu Zhao is the Ira V. Hiscock Professor of Biostatistics, Professor of Genetics, and Professor of Statistics and Data Science at Yale University. He received his BS in…

A genome-wide association study published in G3: Genes|Genomes|Genetics offers insights into the genetic origins of aggression in gamecocks.

Identifying signatures of polygenic adaptation is getting easier—but a commentary calls for caution in drawing conclusions. If you’ve ever wished for a stepstool so you could see the stage at a crowded concert, or, conversely, if you’re tired of being asked “How’s the weather up there?”, you’ve likely pondered what makes some of us tall…

Symptoms of schizophrenia most commonly begin to creep up in young adulthood. Although genetics play a major role in this complex disorder, narrowing down the search for the genes involved has proven frustratingly difficult. Risk loci identified by genome-wide association studies (GWAS) may contain several genes, making it unclear which of these contribute to pathology.…

Chickens that “chicken out” in unfamiliar surroundings may shed light on anxiety in humans, according to research published in the January 2016 issue of the journal GENETICS. Domestic chickens are much less anxious than their wild cousins, the red junglefowl. The new research identifies genes that contribute to this behavioral variation and reveals that several…

As ancient humans spread across the globe from their evolutionary birthplace in Africa, they tended to lose a little genetic diversity at each step along the way. New settlements were probably often founded by small groups that carried only a subset of the total diversity present in their homelands. Successive rounds of this “founder effect”…

By the time President Obama announced the Precision Medicine Initiative in January 2015, the Genetic Epidemiology Research on Adult Health and Aging (GERA) cohort was already a trailblazing example of this new approach to medical research. GERA is a group of more than 100,000 members of the Kaiser Permanente Medical Care Plan who consented to…

The most diverse of all human genes encode a set of proteins at the frontline of our immune system. Many different Human Leukocyte Antigen (HLA) proteins are encoded by genes clumped together in one portion of the human genome known as the major histocompatibility complex region. HLA proteins sit on the surface of cells and…

One of the major risk factors for autoimmune diseases is being born with two copies of the X chromosome. For example, women—who typically carry two Xs—face around ten times the risk of lupus, while men with lupus are around 15 times more likely than the general population to carry two Xs and a Y (Klinefelter…

For genome-wide association studies, data is power. The more data you have, the more statistical power you wield to find genetic associations. But are there ways to get more from the data you already have? In the May issue of GENETICS, Kaufman and Rosset describe a testing framework that substantially boosts the power of genome-wide…
