▶NPT1/SLC17A1 Is a Renal Urate Exporter in Humans and Its Common Gain‐of‐Function Variant Decreases the Risk of Renal Underexcretion GoutAssociationN=3,103Toshinori Chiba et al.(2015)· Arthritis & Rheumatology
This replication study analyzed 2255 variants in LD with GWAS-identified gout/serum urate susceptibility loci in 1255 Han Chinese gout patients and 1848 controls. Twenty-three variants (41%) showed nominal association (p<0.05), with the strongest signal at ABCG2 rs1481012 (p=8.96×10⁻¹¹, OR=1.890). Previous gout-associated loci including ABCG2, SLC2A9, GCKR, ALDH2, and CNIH2 were replicated, while cumulative genetic risk scores showed that individuals with ≥8 risk alleles had significantly increased gout risk (OR=16.361 for ≥12 alleles).
▶Association between gout and polymorphisms in GCKR in male Han ChineseAssociationN=3,103Jing Wang et al.(2012)· Human Genetics
This replication study examined 2,255 variants in linkage disequilibrium with GWAS-identified gout/urate susceptibility loci in 1,255 Han Chinese gout patients and 1,848 controls. Twenty-three variants (41% of 56 LD-pruned variants) showed nominal association with gout (p < 0.05), with the strongest signals at ABCG2 (rs1481012, OR=1.890, p=8.96×10⁻¹¹) and SLC2A9 (rs11722228, OR=1.619, p=2.40×10⁻⁶). Cumulative genetic risk score analysis demonstrated increasing gout risk with growing numbers of risk alleles (OR=16.361 for ≥12 alleles vs ≤5 reference).
About ABCG2
The membrane-associated protein encoded by this gene is included in the superfamily of ATP-binding cassette (ABC) transporters. ABC proteins transport various molecules across extra- and intra-cellular membranes. ABC genes are divided into seven distinct subfamilies (ABC1, MDR/TAP, MRP, ALD, OABP, GCN20, White). This protein is a member of the White subfamily. Alternatively referred to as a breast cancer resistance protein, this protein functions as a xenobiotic transporter which may play a major role in multi-drug resistance. It likely serves as a cellular defense mechanism in response to mitoxantrone and anthracycline exposure. Significant expression of this protein has been observed in the placenta, which may suggest a potential role for this molecule in placenta tissue. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Apr 2012]
