Reactivity of fluoro-substituted bis(thiocarbonyl) donors with diiodine: an XRD, FT-Raman, and DFT investigation.

The reactions of 1,3,8,10-tetrakis(4'-fluorophenyl)-4,5,6,7-tetrathiocino[1,2-b:3,4-b']diimidazolyl-2,9-dithione (4) and molecular diiodine afforded spoke adducts with stoichiometries 4·I2 and 4·3I2 , isolated in the compound 4·3I2·xCH2Cl2·(1-x)I2 (x=0.70), and characterized by single-crystal XRD and FT-Raman spectroscopy. The nature of the reaction products was investigated under the prism of theoretical calculations carried out at the DFT level.

Fine mapping of five loci associated with low-density lipoprotein cholesterol detects variants that double the explained heritability.

Complex trait genome-wide association studies (GWAS) provide an efficient strategy for evaluating large numbers of common variants in large numbers of individuals and for identifying trait-associated variants. Nevertheless, GWAS often leave much of the trait heritability unexplained. We hypothesized that some of this unexplained heritability might be due to common and rare variants that reside in GWAS identified loci but lack appropriate proxies in modern genotyping arrays.

EDA2R is associated with androgenetic alopecia.

Androgenetic alopecia (AGA) is a common heritable polygenic disorder whose genetics is not fully understood, even though it seems to be X-linked. We carried out an epidemiological survey for AGA on 9,000 people from 8 isolated villages of a secluded region of Sardinia (Ogliastra), and identified a large cohort of affected individuals. We genotyped 200 cases and 200 controls (mean kinship 0.

Emergence of Talanin protein associated with human uric acid nephrolithiasis in the Hominidae lineage.

Recently, we identified a susceptibility locus for human uric acid nephrolithiasis (UAN) on 10q21-q22 and demonstrated that a novel gene (ZNF365) included in this region produces through alternative splicing several transcripts coding for four protein isoforms. Mutation analysis showed that one of them (Talanin) is associated with UAN. We examined the evolutionary conservation of ZNF365 gene through a comparative genomic approach.

Identification of a novel gene and a common variant associated with uric acid nephrolithiasis in a Sardinian genetic isolate.

Uric acid nephrolithiasis (UAN) is a common disease with an established genetic component that presents a complex mode of inheritance. While studying an ancient founder population in Talana, a village in Sardinia, we recently identified a susceptibility locus of approximately 2.5 cM for UAN on 10q21-q22 in a relatively small sample that was carefully selected through genealogical information.
