Familial hemiplegic migraine and episodic ataxia type-2 are caused by mutations in the Ca2+ channel gene CACNL1A4

RA Ophoff, GM Terwindt, MN Vergouwe, R van Eijk… - Cell, 1996 - cell.com
Genes for familial hemiplegic migraine (FHM) and episodic ataxia type-2 (EA-2) have been
mapped to chromosome 19p13. We characterized a brain-specific P/Q-type Ca 2+ channel …

Biological insights from 108 schizophrenia-associated genetic loci

…, PB Mortensen, BJ Mowry, MM Nöthen, RA Ophoff… - Nature, 2014 - nature.com
Schizophrenia is a highly heritable disorder. Genetic risk is conferred by a large number of
alleles, including common alleles of small effect that might be detected by genome-wide …

Common variants conferring risk of schizophrenia

H Stefansson, RA Ophoff, S Steinberg, OA Andreassen… - Nature, 2009 - nature.com
Schizophrenia is a complex disorder, caused by both genetic and environmental factors and
their interactions. Research on pathogenesis has traditionally focused on neurotransmitter …

Large recurrent microdeletions associated with schizophrenia

…, A Kong, OA Andreassen, RA Ophoff… - nature, 2008 - nature.com
Reduced fecundity, associated with severe mental disorders 1 , places negative selection
pressure on risk alleles and may explain, in part, why common variants have not been found …

Rare coding variants in ten genes confer substantial risk for schizophrenia

…, MP Vawter, JT Walters, TM Werge, RA Ophoff… - Nature, 2022 - nature.com
Rare coding variation has historically provided the most direct connections between gene
function and disease pathogenesis. By meta-analysing the whole exomes of 24,248 …

Meta-analysis identifies 29 additional ulcerative colitis risk loci, increasing the number of confirmed associations to 47

…, KI Morley, C Mowat, A Ng, W Newman, RA Ophoff… - Nature …, 2011 - nature.com
Genome-wide association studies and candidate gene studies in ulcerative colitis have
identified 18 susceptibility loci. We conducted a meta-analysis of six ulcerative colitis genome-…

Multiple common variants for celiac disease influencing immune gene expression

…, JA Murray, C Núñez, E Oosterom, RA Ophoff… - Nature …, 2010 - nature.com
We performed a second-generation genome-wide association study of 4,533 individuals with
celiac disease (cases) and 10,750 control subjects. We genotyped 113 selected SNPs with …
