Non-insulin-dependent diabetes mellitus (NIDDM) affects about 5% of the world population. The disease presents a polygenic mode of inheritance, but mechanisms and genes involved in late-onset NIDDM are largely unknown. We report the association of a single heterozygous Gly to Ser missense mutation in the glucagon receptor gene with late-onset NIDDM. This(More)
BACKGROUND Hypersensitivity reaction to nevirapine, which in some cases can be fatal, shows a higher prevalence in Sardinia in comparison with other Italian regions. OBJECTIVE This study demonstrates that hypersensitive reaction to nevirapine in Sardinian HIV-infected patients is associated with the HLA Cw8-B14 haplotype. These two HLA class I antigens(More)
BACKGROUND In this study, the apolipoprotein E (apoE) genotypes as well as plasma lipid and lipoprotein levels have been determined for the first time in 633 healthy and unrelated inhabitants on the island of Sardinia (291 men and 342 women, age range 6-89 years), randomly selected in the four districts of Sardinia among healthy people having parents and(More)
Fifty-three French families were typed for alleles at seven loci of the HLA complex (HLA-A, -B, -C, -DR, -Bf, -C2 and -GLO) and 212 haplotypes were demonstrated. Eleven recombinations were observed (two A/B, two A/C, two B/Bf, one Bf/D and four D/GLO). The linkage disequilibrium was calculated not only between two alleles (delta) but between three,(More)
Numerous putative susceptibility loci have been described for psoriasis. Among the loci confirmed in the literature, PSORS1 (the major histocompatibility complex at 6p21.3) has the strongest effect. Recent studies have highlighted a 200-kb candidate region. However, this region has not been well delimited, mainly because of the strong linkage equilibrium(More)
This study characterizes by serological and molecular methods the HLA class I and class II alleles in a group of celiac disease children, their parents and a control group of Sardinian descent. We found the DR3-DQw2 haplotype in all patients which was, in almost all cases (84%), associated with the HLA-A30, B18, DR3, DRw52, DQw2 extended haplotype named(More)
From 1902 to 1983, 68 cases of hepatolenticular degeneration (HLD) were discovered in Sardinia, with a mean frequency, in reference to number of live births, of 27.7 and a sex ratio of 1.83. The prevalence of the disease was seen to be higher over the last few decades. With regard to the geographic distribution of the disease, 3 high-frequency areas were(More)
