    Autoimmune diabetes mellitus with adult onset and type 1 diabetes mellitus in children have different genetic predispositions

  • Original language description

    Type 1 diabetes with manifestation after 35 years of age is defined by CP <200 pmol/L and institution of insulin therapy within 6 months after diagnosis. Latent autoimmune diabetes mellitus in adults (LADA) manifesting after 35 years of age is defined byminimum 6 months after diagnosis without insulin therapy and C peptide (CP) >200 pmol/L and antiGAD > 50 ng/mL. We aimed to find a possible genetic discrimination among different types of autoimmune diabetes. To accomplish this goal, we analyzed DNA samples from 31 LADA patients, 75 patients with adult-onset type 1 diabetes mellitus, 188 type 1 diabetic children, and 153 healthy adult individuals. We studied five genetic loci on chromosomes 6, 11, 4, and 14: HLA DRB1 and DQB1 alleles, major histocompatibility complex (MHC) class I-related gene-A (MIC-A) microsatellite polymorphism, interleukin (IL)-18 single nucleotide polymorphism, the microsatellite polymorphism of nuclear factor kappa B gene (NF-kappaB1), and the single nucleotide p

    Autoimunitní diabetes mellitus manifestovaný v dospělosti a typ 1 diabetes mellitus u dětí mají odlišné genetické predispozice

  • Czech description

    Cílem této studie bylo geneticky rozlišit různé typy autoimunitního diabetes mellitus (DM): LADA, T1DM s nástupem v dospělosti a T1DM u dětí. Sledovali jsme 5 genetických lokusů: alely HLA DRB1 a DQB1, MIC-A mikrosatelitní polymorfismus, interleukin (IL)-18 SNP, mikrosatelitní polymorfismus genu pro NF-kappaB1a SNP v genu pro jeho inhibitor (NF-kappaBIA). Pro LADA diabetes jsou predispozičními alela HLA-DR3 (OR = 4.94, P < 0.0001) a genotyp AA NF-kappaBIA (OR = 2.68, P < 0.01). HLA DRB1*04 a HLA DQB1*0302 byly zjištěny jako rizikové faktory pro DM manifestovaný po 35. roce (OR = 10.47, P < 0.0001 a OR = 9.49, P < 0.0001). S tímto typem DM byla asociována také alela MIC-A5.1 (OR = 2.14, P < 0.01). LADA a T1DM u dospělých se lišily ve frekvenci polymorfismu -607 C/A promotoru IL-18 genu (P < 0.01). Lze tedy říci, že všechny podskupiny autoimunitního diabetes mají částečně odlišné imunogenetické predispozice.
