Part of this study was funded by European Research Council grant ERC-2012-ADG_20120314 (grant agreement 322947) and Agence Nationale pour la Recherche “Genetransnephrose” grant ANR-16-CE17-004-01 to PR. RG is supported by National Institutes of Health / National Institutes of Diabetes and Digestive and Kidney Diseases (NIH/NIDDK) grants 5R01DK098135 and 5R01DK094987 , the Doris Duke Charitable Foundation Clinical Scientist Development Award 2009033, and a Duke Health Scholars award. MGS is supported by a National Institutes of Health grant ( R01-DK108805 ). The Nephrotic Syndrome Study Network Consortium (NEPTUNE; U54-DK-083912) is a part of the National Center for Advancing Translational Sciences (NCATS). The Rare Disease Clinical Research Network (RDCRN) was supported through a collaboration between the Office of Rare Diseases Research (ORDR), NCATS, and the National Institute of Diabetes, Digestive, and Kidney Diseases. The RDCRN is an initiative of the ORDR of NCATS. Additional funding and/or programmatic support for this project was provided by the University of Michigan, NephCure Kidney International, and the Halpin Foundation. The NEPHROVIR cohort was supported by 2 grants to Georges Deschênes from the Programme Hospitalier de Recherche Clinique: grants PHRC 2007-AOM07018 and PHRC 2011-AOM11002. The NEPHROVIR network is coordinated by the Pediatric Nephrology Unit of Robert Debré Hospital, the “Unité de Recherche Clinique de l’Est Parisien,” and the “Délégation de la Recherche Clinique de la Région Ile-de-France.” Marina Vivarelli was supported by the Associazione per la Cura del bambino Nefropatico ONLUS (Organizzazione Non Lucrativa di Utilità Sociale).

N2 - To understand the genetics of steroid-sensitive nephrotic syndrome (SSNS), we conducted a genome-wide association study in 987 childhood SSNS patients and 3,206 healthy controls with Japanese ancestry. Beyond known associations in the HLA-DR/DQ region, common variants in NPHS1-KIRREL2 (rs56117924, P=4.94E-20, odds ratio (OR) =1.90) and TNFSF15 (rs6478109, P=2.54E-8, OR=0.72) regions achieved genome-wide significance and were replicated in Korean, South Asian and African populations. Trans-ethnic meta-analyses including Japanese, Korean, South Asian, African, European, Hispanic and Maghrebian populations confirmed the significant associations of variants in NPHS1-KIRREL2 (Pmeta=6.71E-28, OR=1.88) and TNFSF15 (Pmeta=5.40E-11, OR=1.33) loci. Analysis of the NPHS1 risk alleles with glomerular NPHS1 mRNA expression from the same person revealed allele specific expression with significantly lower expression of the transcript derived from the risk haplotype (Wilcox test p=9.3E-4). Because rare pathogenic variants in NPHS1 cause congenital nephrotic syndrome of the Finnish type (CNSF), the present study provides further evidence that variation along the allele frequency spectrum in the same gene can cause or contribute to both a rare monogenic disease (CNSF) and a more complex, polygenic disease (SSNS).
