Both genetic regulation of immune cell levels and their relationships with autoimmunity are largely undetermined. Here, we report genetic contributions to quantitative levels of 95 cell types encompassing 272 immune traits, in a cohort of 1,629 individuals from four clustered Sardinian villages. We first estimated trait heritability, showing that it can be substantial, accounting for up to 87% of the variance (mean 41%). Next, by assessing ∼8.2 million variants that we identified and confirmed in an extended set of 2,870 individuals, 23 independent variants at 13 loci associated with at least one trait. Notably, variants at three loci (HLA, IL2RA, and SH2B3/ATXN2) overlap with known autoimmune disease associations. These results connect specific cellular phenotypes to specific genetic variants, helping to explicate their involvement in disease."],"pubmed_title":["Genetic variants regulating immune cell levels in health and disease."],"pubmed_authors":["Orrù Valeria V, Steri Maristella M, Sole Gabriella G, Sidore Carlo C, Virdis Francesca F, Dei Mariano M, Lai Sandra S, Zoledziewska Magdalena M, Busonero Fabio F, Mulas Antonella A, Floris Matteo M, Mentzen Wieslawa I WI, Urru Silvana A M SA, Olla Stefania S, Marongiu Michele M, Piras Maria G MG, Lobina Monia M, Maschio Andrea A, Pitzalis Maristella M, Urru Maria F MF, Marcelli Marco M, Cusano Roberto R, Deidda Francesca F, Serra Valentina V, Oppo Manuela M, Pilu Rosella R, Reinier Frederic F, Berutti Riccardo R, Pireddu Luca L, Zara Ilenia I, Porcu Eleonora E, Kwong Alan A, Brennan Christine C, Tarrier Brendan B, Lyons Robert R, Kang Hyun M HM, Uzzau Sergio S, Atzeni Rossano R, Valentini Maria M, Firinu Davide D, Leoni Lidia L, Rotta Gianluca G, Naitza Silvia S, Angius Andrea A, Angius Andrea A, Congia Mauro M, Whalen Michael B MB, Jones Chris M CM, Schlessinger David D, Abecasis Gonçalo R GR, Fiorillo Edoardo E, Sanna Serena S, Cucca Francesco F"],"additional_accession":[]},"is_claimable":false,"name":"DAC for Sardinia FACS pilot project","description":"Data Access Committee EGAC00001000132","dates":{"output":"2025-1-9"},"accession":"EGAC00001000132","cross_references":{"TAXONOMY":["9606"],"pubmed":["24074872"],"EGA":["EGAS00001000574","EGAD00001000656"]}}
