LAR , a protein-tyrosine phosphatase which inhibits insulin signalling, is overexpressed in animal and human models of insulin resistance. We studied the entire sequence of the LAR gene by SSCP analysis and automatic DNA sequencing, with the aim of verifying whether its sequence variants might be associated with insulin resistance. In the 276 bp sequence upstream of the transcriptional start site (i.e. a region we have identified as having basal promoter activity) a -127 bp T-->A SNP (5% frequency) was associated with lower body mass index (BMI) ( P=0.03), waist circumference ( P=0.01), blood pressure ( P=0.01) and urinary albumin/creatinine ratio ( P=0.04) in 589 non-diabetic unrelated individuals from the Gargano region (central east coast of Italy). To quantify the risk for a high body weight conferred by the -127 T-->A SNP, the whole cohort was divided into tertiles according to the individual BMI. The risk of belonging to the heavier tertile, as compared to the leaner one, was reduced by approximately 60%. In a population from East Sicily ( n=307), T/A genotype carriers ( n=13) showed lower triglyceride levels ( P=0.04) and higher insulin sensitivity as indicated by lower plasma glucose ( P=0.03) and serum insulin ( P=0.006) during oral glucose tolerance testing (OGTT). Promoter activity, studied by cDNA transfection experiments, was similar for the A and T alleles. In conclusion, a genetic variant of the LAR gene promoter is consistently associated with features of insulin resistance in two different Caucasian populations. Although the biological relevance of this variant has yet to be determined, this finding underlines the potential importance of the LAR gene in dysregulation of insulin sensitivity and related disorders." ], "offsets": [ [ 154, 2067 ] ] } ]

Recent studies have shown that polymorphisms in the SCN5A gene also play an important role in the manifestation of disorders involving cardiac excitability. In this study, we investigated the polymorphisms of the SCN5A gene in Han Chinese and its relation to Brugada syndrome (BS). METHODS: Genomic DNA was isolated from 120 unrelated healthy volunteers and 48 unrelated Brugada syndrome patients by means of standard procedures. All exons including the putative splicing sites of the SCN5A gene were amplified by PCR and sequenced directly or after subcloning using an ABI Prism 377 DNA sequencer. RESULTS: A total of 5 single nucleotide polymorphisms (SNPs) were identified in the Han Chinese population, including 3 novel ones: G87A (A29A) , 4245 + 82A > G , and G6174A . The allele frequencies of each SNP in the Han Chinese population were as follows: G87A (A29A) 27.5%, A1673G (H558R) 10.4%, 4245 + 82A > G 32.8%, C5457T (D1819D) 41.3%, and G6174A 44.9%. S1102Y and 10 other SNPs identified in other ethnic populations were not detected in this study. There was no significant difference in the allele frequency of A1673G (H558R) between different ethnic populations (all P > 0.5). On the other hand, the allele frequency of C5457T (D1819D) among Han Chinese was similar to its frequency among Japanese (P > 0.5), but higher than that among Americans (P < 0.005). The allele G1673 (R558) was over-represented in BS patients compared to controls (P < 0.005), but there was no significant difference in genotype frequencies at this locus. There were also no differences in either the allele or genotype frequencies of the 4 other identified SNPs when comparing BS patients with healthy controls. CONCLUSIONS: The distribution of SCN5A SNPs may vary between different ethnicities. The polymorphism of A1673G might be associated with BS and may contribute to a susceptibility to BS in Han Chinese." ], "offsets": [ [ 109, 2300 ] ] } ]

This was confirmed in samples of mainly United Kingdom (UK) origin. In this study, we performed both mutation analysis and association studies in order to evaluate the role of this gene in a collection of isolated Belgian PDB patients. A mutation in the SQSTM1 gene was found in only 6 of 111 patients (5.4%). In all cases it involves the P392L mutation, previously shown to be common in both familial and sporadic cases. To perform association studies, we selected 8 single nucleotide polymorphisms (SNPs) and looked for linkage disequilibrium (LD) between these. Haplotype analysis indicated that typing of 3 Tag SNPs ( IVS1 + 633A/C , IVS5 - 23A/G , and 976A/G ) enables us to identify the most common haplotypes. Association studies for the 3 selected SNPs, based on 105 PDB cases without a SQSTM1 mutation and 159 control individuals, did not support a possible influence of natural variants in the SQSTM1 gene either on the pathogenesis of PDB or on the disease severity. In conclusion, our study confirms that the P392L mutation is a recurrent mutation causing PDB in different populations. We were not able to show an association between SQSTM1 polymorphisms and PDB in our population but this clearly needs to be extended to other populations. The presented identification of haplotype Tag SNPs will be of major help for such studies." ], "offsets": [ [ 95, 1680 ] ] } ]

METHODS: In a case-control study, genotypes of 130 patients with JIA (63 male, 67 female; age at onset 7.6 +/- 4.4 yrs; 43 oligoarticular, 72 polyarticular, 15 systemic form) were compared to 102 healthy unrelated blood donors. Using the polymerase chain reaction technique with sequence-specific primers from the 13th IHWG workshop, we analyzed 19 single nucleotide polymorphisms within 12 different cytokine genes [ interleukin (IL)-1a , IL-1beta , IL-2 , IL-4 , IL-6 , IL-10 , IL-12 , transforming growth factor (TGF)-beta , interferon (IFN)-g ], and related molecules ( IL-1R , IL-1RA , IL-4Ra ). Genotype frequencies were compared using chi-square analysis, and the significance level was corrected for the number of independent tests. RESULTS: Significant positive association was found for the G allele of the IL-4 -1098 T/G polymorphism, which was carried by 10% of cases and 25% of controls [odds ratio (OR) 0.32, 95% confidence interval (CI) 0.16-0.67, corrected p = 0.038). Also, a nonsignificant increase in the frequency of the IL-1beta +3962 C allele was detected in cases (96%) versus controls (84%) (OR 4.65, 95% CI 1.64-13.2, corrected p = 0.091). We did not replicate previously found associations with the IL-1a , IL-6 , IL-10 , and IL-1R IL-1RA polymorphisms. CONCLUSION: Our study showed association with JIA for the IL-4 -1098 T/G polymorphism. It also underlines the genetic contribution of IL-1 polymorphisms to the pathogenesis of JIA, as another polymorphism within the IL-1beta may influence the risk of the disease." ], "offsets": [ [ 129, 1853 ] ] } ]
