GRS of BP traits were associated with BI and SSBI (p = 0.0022), without indication of directional pleiotropy. Conclusion: In this multiethnic GWAS meta-analysis, including over 20,000 population-based participants, we identified genetic risk loci for BI requiring validation once additional large datasets become available. High BP, including genetically determined, was the most significant modifiable, causal risk factor for BI.]]> Wed 04 Aug 2021 10:54:18 AEST ]]> Comparison of HapMap and 1000 genomes reference panels in a large-scale genome-wide association study https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:30590 Tue 20 Aug 2024 12:05:56 AEST ]]> 1000 genomes-based meta-analysis identifies 10 novel loci for kidney function https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:30822 50 loci at which common variants with minor allele frequency >5% are associated with kidney function. GWAS using more complete reference sets for imputation, such as those from The 1000 Genomes project, promise to identify novel loci that have been missed by previous efforts. To investigate the value of such a more complete variant catalog, we conducted a GWAS meta-analysis of kidney function based on the estimated glomerular filtration rate (eGFR) in 110,517 European ancestry participants using 1000 Genomes imputed data. We identified 10 novel loci with p-value < 5 × 10−8 previously missed by HapMap-based GWAS. Six of these loci (HOXD8, ARL15, PIK3R1, EYA4, ASTN2, and EPB41L3) are tagged by common SNPs unique to the 1000 Genomes reference panel. Using pathway analysis, we identified 39 significant (FDR < 0.05) genes and 127 significantly (FDR < 0.05) enriched gene sets, which were missed by our previous analyses. Among those, the 10 identified novel genes are part of pathways of kidney development, carbohydrate metabolism, cardiac septum development and glucose metabolism. These results highlight the utility of re-imputing from denser reference panels, until whole-genome sequencing becomes feasible in large samples.]]> Tue 04 Apr 2023 19:09:51 AEST ]]> Genome-wide association study of kidney function decline in individuals of European descent. https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:17347 Sat 24 Mar 2018 08:01:42 AEDT ]]> Genetic determinants of heel bone properties: genome-wide association meta-analysis and replication in the GEFOS/GENOMOS consortium https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:20501 Sat 24 Mar 2018 07:59:03 AEDT ]]> Genome-wide association analysis identifies six new loci associated with forced vital capacity https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:21233 P < 5 × 10−8) with FVC in or near EFEMP1, BMP6, MIR129-2–HSD17B12, PRDM11, WWOX and KCNJ2. Two loci previously associated with spirometric measures (GSTCD and PTCH1) were related to FVC. Newly implicated regions were followed up in samples from African-American, Korean, Chinese and Hispanic individuals. We detected transcripts for all six newly implicated genes in human lung tissue. The new loci may inform mechanisms involved in lung development and the pathogenesis of restrictive lung disease.]]> Sat 24 Mar 2018 07:53:01 AEDT ]]> Genome-wide association analyses identify 18 new loci associated with serum urate concentrations https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:28431 140,000 individuals of European ancestry within the Global Urate Genetics Consortium (GUGC), we identified and replicated 28 genome-wide significant loci in association with serum urate concentrations (18 new regions in or near TRIM46, INHBB, SFMBT1, TMEM171, VEGFA, BAZ1B, PRKAG2, STC1, HNF4G, A1CF, ATXN2, UBE2Q2, IGF1R, NFAT5, MAF, HLF, ACVR1B-ACVRL1 and B3GNT4). Associations for many of the loci were of similar magnitude in individuals of non-European ancestry. We further characterized these loci for associations with gout, transcript expression and the fractional excretion of urate. Network analyses implicate the inhibins-activins signaling pathways and glucose metabolism in systemic urate control. New candidate genes for serum urate concentration highlight the importance of metabolic control of urate production and excretion, which may have implications for the treatment and prevention of gout.]]> Sat 24 Mar 2018 07:29:03 AEDT ]]> Common variants in mendelian kidney disease genes and their association with renal function https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:23785 5%) within these genes for association with the estimated GFR in 74,354 European-ancestry participants from the CKDGen Consortium. However, the top four candidate SNPs (rs6433115 at LRP2, rs1050700 at TSC1, rs249942 at PALB2, and rs9827843 at ROBO2) did not achieve significance in a stage 2meta-analysis performed in 56,246 additional independent individuals, indicating that these common SNPs are not associated with estimated GFR. The effect of less common or rare variants in these genes on kidney function in the general population and disease-specific cohorts requires further research.]]> Sat 24 Mar 2018 07:16:26 AEDT ]]> Integration of genome-wide association studies with biological knowledge identifies six novel genes related to kidney function https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:22322 FBXL20 (P = 5.6 × 10−9) in meta-analysis of all available data, and additional SNPs at the INHBC, LRP2, PLEKHA1, SLC3A2 and SLC7A6 genes meeting multiple-testing corrected significance for replication and overall P-values of 4.5 × 10−4–2.2 × 10−7. Neither the novel PLEKHA1 nor FBXL20 associations, both further supported by association with eGFR among African Americans and with transcript abundance, would have been implicated by eGFR candidate gene approaches. LRP2, encoding the megalin receptor, was identified through connection with the previously known eGFR gene DAB2 and extends understanding of the megalin system in kidney function. These findings highlight integration of existing genome-wide association data with independent biological knowledge to uncover novel candidate eGFR associations, including candidates lacking known connections to kidney-specific pathways. The strategy may also be applicable to other clinical phenotypes, although more testing will be needed to assess its potential for discovery in general.]]> Sat 24 Mar 2018 07:14:43 AEDT ]]> Genetic associations at 53 loci highlight cell types and biological pathways relevant for kidney function https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:30005 Mon 17 Oct 2022 12:06:14 AEDT ]]>
