Abstract

We fine mapped two primary biliary cirrhosis (PBC) risk loci, CLEC16A (C-type lectin domain family 16 member A)-suppressor of cytokine signaling 1 (SOCS1) and Spi-B protein (SPIB) and sequenced a locus, sialic acid acetylesterase (SIAE), proposed to harbor autoimmunity-associated mutations. In all, 1450 PBC cases and 2957 healthy controls were genotyped for 84 single-nucleotide polymorphisms (SNPs) across the CLEC16A-SOCS1 and SPIB loci. All 10 exons of the SIAE gene were resequenced in 381 cases and point substitutions of unknown significance assayed for activity and secretion. Fine mapping identified 26 SNPs across the CLEC16A-SOCS1 and 11 SNPs across the SPIB locus with significant association to PBC, the strongest signals at the CLEC16A-SOCS1 locus emanating from a SOCS1 intergenic SNP (rs243325; P=9.91 × 10(-9)) and at the SPIB locus from a SPIB intronic SNP (rs34944112; P=3.65 × 10(-9)). Among the associated SNPs at the CLEC16A-SOCS1 locus, two within the CLEC16A gene as well as one SOCS1 SNP (rs243325) remained significant after conditional logistic regression and contributed independently to risk. Sequencing of the SIAE gene and functional assays of newly identified variants revealed six patients with functional non-synonymous SIAE mutations (Fisher's P=9 × 10(-4) vs controls) We demonstrate independent effects on risk of PBC for CLEC16A, SOCS1 and SPIB variants, while identifying functionally defective SIAE variants as potential factors in risk for PBC.

  • The presence of genetic susceptibility is supported by the increased concordance rate in monozygotic twins and confirmed by the identification of significant numbers of associated genetic loci in GWAS and other large-scale genetic approaches.

    “The presence of genetic susceptibility is supported by the increased concordance rate in monozygotic twins44 and confirmed by the identification of significant numbers of associated genetic loci in Genome Wide Association Studies (GWAS) and other large-scale, high-quality genetic approaches.45–54”

  • Alleles of the CLEC16A gene confer risk for autoimmune diseases including type 1 diabetes, multiple sclerosis, primary adrenal insufficiency, primary biliary cirrhosis, alopecia areata, juvenile idiopathic arthritis and rheumatoid arthritis.

    “Genome-wide association studies (GWAS) demonstrate that alleles of the CLEC16A gene (also KIAA0350) confer risk for autoimmune diseases including type 1 diabetes, multiple sclerosis, primary adrenal insufficiency, primary biliary cirrhosis, alopecia areata, juvenile idiopathic arthritis and rheumatoid arthritis1234567.”

    From Clec16a is Critical for Autolysosome Function and Purkinje Cell Survival (2016) · cites this paper as [3]

    The Introduction (page unavailable) identifies CLEC16A, also called KIAA0350, within a locus associated with type 1 diabetes, multiple sclerosis and primary biliary cirrhosis; it also reports variants within CLEC16A that contribute to PBC risk. Our copy does not link CLEC16A alleles to primary adrenal insufficiency, alopecia areata, juvenile idiopathic arthritis or rheumatoid arthritis. Its mention of rheumatoid arthritis concerns other immune-related loci or SIAE, not specifically CLEC16A. (LLM, conf=0.88)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
