Two <jats:italic>CXADR<\/jats:italic> single nucleotide polymorphisms (SNPs), rs6517774 and rs2824404, were previously associated with an increased susceptibility to IA in the international TEDDY study (The Environmental Determinants of Diabetes in the Young). This study aimed to replicate the results by genotyping 2886 children enrolled in the Finnish Diabetes Prediction and Prevention study (DIPP). In our preliminary analysis of the SNPs\u2019 allelic distributions, we could not find any association with IA susceptibility. However, a stratified analysis revealed a sex disparity, since the allelic distribution of rs6517774 was different when comparing autoantibody positive females with males; a difference not seen in healthy subjects. By using HLA risk groups and sex as covariates, a Cox regression survival analysis found that the rs6517774 (A\/G) SNP was associated with a lower age at seroconversion in females (Female*rs6517774-AA; HR = 1.53, <jats:italic>p<\/jats:italic> = 0.002), while introducing a protective effect in males. Accordingly, we propose that rs6517774 alters IA characteristics by modifying the age at seroconversion in a sex-dependent manner. In light of this observation, rs6517774 now joins a limited set on SNPs found to introduce sex-dependent risk effects on the age at IA initiation.<\/jats:p>","DOI":"10.3389\/fgene.2023.1248701","type":"journal-article","created":{"date-parts":[[2023,11,2]],"date-time":"2023-11-02T09:11:11Z","timestamp":1698916271000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["CXADR polymorphism rs6517774 modifies islet autoimmunity characteristics and exhibits sex disparity"],"prefix":"10.3389","volume":"14","author":[{"given":"Lucas","family":"Nyg\u00e5rd","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Milla","family":"Valta","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Antti-Pekka","family":"Laine","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jorma","family":"Toppari","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mikael","family":"Knip","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Riitta","family":"Veijola","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Heikki","family":"Hy\u00f6ty","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jorma","family":"Ilonen","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Johanna","family":"Lempainen","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1965","published-online":{"date-parts":[[2023,11,2]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"516365","DOI":"10.1101\/2022.11.14.516365","article-title":"FORGEdb: a tool for identifying candidate functional variants and uncovering target genes and mechanisms for complex","volume":"11","author":"Breeze","year":"2023","journal-title":"bioRxiv"},{"key":"B2","unstructured":"Type 1 diabetes prediction and prevention (DIPP) study2023"},{"key":"B3","doi-asserted-by":"publisher","first-page":"724","DOI":"10.1038\/s41588-023-01365-3","article-title":"Annotating and prioritizing human non-coding variants with RegulomeDB v.2","volume":"55","author":"Dong","year":"2023","journal-title":"Nat.
