positively associated with type 1 diabetes and other autoimmune

effect, but some studies suggest that this polymorphism does not
entirely explain disease association of the PTPN22 region. The
aim of this study was to evaluate type 1 diabetes association
within this gene in the Sardinian population. RESEARCH DESIGN
AND METHODS: We resequenced the exons and potentially relevant
portions of PTPN22 and detected 24 polymorphisms (23 SNPs and 1
deletion insertion polymorphism [DIP]), 8 of which were novel. A
representative set of 14 SNPs and the DIP were sequentially
genotyped and assessed for disease association in 794 families,
490 sporadic patients, and 721 matched control subjects.
RESULTS: The +1858C>T variant, albeit rare in the general
Sardinian population (allele frequency 0.014), was positively associated with type 1 diabetes (P(one tail) = 3.7 x 10(-3)). In
contrast, the background haplotype in which this mutation
occurred was common (haplotype frequency 0.117) and neutrally
associated with disease. We did not confirm disease associations
reported in other populations for non +1858C>T variants
(rs2488457, rs1310182, and rs3811021), although they were
present in appreciable frequencies in Sardinia. Additional weak
disease associations with rare variants were detected in the
Sardinian families but not confirmed in independent case-control
sample sets and are most likely spurious. CONCLUSIONS: We
provide further evidence that the +1858C>T polymorphism is
primarily associated with type 1 diabetes and exclude major
contributions from other purportedly relevant variants within

METHODS: Genetic testing was compared to an improved test obtained by a combination of different breath hydrogen tests and clinical assessment. RESULTS: We found that all 49 individuals with lactose malabsorption, demonstrated by a combination of different breath hydrogen tests and clinical assessment, carried the C/C-13910 genotype associated with lactase non-persistence, 23 individuals with lactose normal absorption carried the C/T-13910 genotype associated with lactase persistence and only one person with the above phenotype showed a discordant C/C-13910 genotype. The genetic testing showed very high sensitivity, specificity, positive and negative predictive values of 100, 95.8, 98 and 100%, respectively. CONCLUSIONS: Sardinians, unlike some ethnic groups in sub-Saharan Africa, show the same genetic association of hypolactasia with the C/T-13910 variant as other North-European populations.

Comparison of the mutation spectra of Crisponi syndrome and CISS1 suggests that neither the type nor the location of the CRLF1 mutations points to a phenotype/genotype correlation that would account for the most severe phenotype in Crisponi syndrome. Other, still-unknown molecular factors may be responsible for the variable phenotypic expression of the CRLF1 mutations.

To verify the association between serum zonulin levels and in vivo intestinal permeability in patients with type 1 diabetes, both parameters were investigated in different stages of the autoimmune process. Forty-two percent (141 of 339) of the patients had abnormal serum zonulin levels, as compared with age-matched control subjects.

Zonulin, a protein that modulates intestinal permeability, is upregulated in several autoimmune diseases and is involved in the pathogenesis of autoimmune diabetes in the BB/Wor animal model of the disease. To verify the association between serum zonulin levels and in vivo intestinal permeability in patients with type 1 diabetes, both parameters were investigated in different stages of the autoimmune process. Forty-two percent (141 of 339) of the patients had abnormal serum zonulin levels, as compared with age-matched control subjects.

In the mouse model of type 1 diabetes, susceptibility was also associated with variation in CTLA-4 gene splicing with reduced production of a splice form encoding a molecule lacking the CD80/CD86 ligand-binding domain. Genetic mapping of variants conferring a small disease risk can identify pathways in complex disorders, as exemplified by our discovery of inherited, quantitative alterations of CTLA4 contributing to autoimmune tissue destruction. |
