To summarize the clinical characteristics of two children with nonclassical 21 hydroxylase deficiency (NC-21OHD) due to variants of CYP21A2 gene promoter region.

Clinical characteristics and the results of genetic testing were reviewed.

The main clinical manifestations of the two children included precocious puberty with poor bone age/progression control and menstrual disorder with hirsutism. Patient 1 had compound heterozygous variants for -126C>T, -113G>A, -110T>C and p.I173N; her mother was heterozygous for -126C>T, -113G>A and -110T>C, and her father was heterozygous for p.I173N. Patient 2 had compound heterozygous variants for -126C>T, -113G>A and p.I2G, whose mother was heterozygous for -126C>T and -113G>A, and father was heterozygous for p.I2G.

Diagnosis of NC-21OHD should be considered for children with hirsutism, menstrual disorder and poor bone age/progression control. The promoter region of CYP21A2 gene should be analyzed when no variant is detected in its coding regions.

To develop a cell-based system for the diagnosis of vitamin K-dependent coagulation factor deficiency 1 (VKCFD1).

In HEK293 cells stably expressing the reporter gene FIX-Gla-PC, the gamma-glutamyl carboxylase (GGCX) gene was knocked out by using CRISPR/Cas9 technology. Tamoxifen manufacturer Enzyme-linked immunosorbent assay (ELISA), DNA sequencing and Western blotting were used to identify the GGCX gene knockout cells. A quickchange point variant method was used to construct the GGCX variant. ELISA was used to assess the influence of GGCX variant on the activity of reporter gene.

Two monoclonal cell lines with no reporter activity by ELISA was identified. Edition and knockout of the GGCX gene was confirmed by DNA sequencing and Western blotting. The activity of the reporter gene was recovered by transfection of the wild-type GGCX gene. Thereby two monoclonal cells with GGCX knockout were obtained. By comparing the wild-type and pathogenic GGCX variants, the reporter activity was decreased in the pathogenic variants significantly.

A cell-based system for the detection of GGCX activity was successfully developed, which can be used for the diagnosis of VKCFD1 caused by GGCX variants.

To explore the genetic basis for a pedigree affected with Alport syndrome.

Next generation sequencing and Sanger sequencing was carried out to detect potential variant of the COL4A5 gene among members from the pedigree and 100 unrelated healthy controls.

A novel missense c.3293G>T (p.Gly1098Val) variant was found in the COL4A5 gene among 6 affected members but not the unaffected members of the pedigree or the 100 healthy controls. According to the American College of Medical Genetics and Genomics standards and guidelines, the c.3293G>T variant was classified as pathogenic (PP1-strong+PM1+PM2+PP3+PP4).

By destructing the Gly-X-Y structure of its protein product, the c.3293G>T variant of the COL4A5 gene probably underlies the Alport syndrome in this pedigree. Above finding has enriched the spectrum of COL4A5 variants.

Above finding has enriched the spectrum of COL4A5 variants.Previous studies led to identify SNPs in putative regulatory regions of the SLC11A1 and CARD15 genes with association to paratuberculosis in cattle. Aim of this study was to investigate the role of these mutations at the regulatory level by DNA-protein interaction analyses and transcriptome comparison between wild-type and mutated animals. Gene regions carrying the SNPs of interest were analysed by bioinformatic tools to predict allele-dependent binding sites for transcription factors (TFBS). Putative TFBS were in vitro explored by Electrophoretic Mobility Shift Assays (EMSA). EMSA did not show specific gel shifts for any allele indicating that these SNPs may eventually influence gene transcription without altering TFBS. Whole transcriptome expression analysis was performed on intestinal tissues of wild-type and mutated cattle by RNA-Seq. Differential regulation of five genes involved in innate immune system was detected. Specifically, ULBP3 was down-regulated, while S100A8, S100A12, LOC510860, and IFI27 were up-regulated. In previous studies, ULBP3, S100A8, and S100A12 resulted differentially expressed in cattle affected by paratuberculosis, suggesting a possible implication in the pathogen response. Further investigations are needed to elucidate the functional role of these SNPs and to understand the gene network involved in the interactions between non-coding SNPs and other genome regions.Dogs are the major reservoir of Leishmania infantum, the causative agent of canine visceral and cutaneous human leishmaniasis in the Mediterranean basin. Canine and human leishmaniosis are endemic in Italy, particularly in central and southern regions, including islands. Here we show a preliminary, clinical, serological and molecular study carried out in Pantelleria island during 2017. In this study, we clinically examined 136 dogs for the presence of symptoms compatible with leishmaniasis, determined the titer of anti‑Leishmania antibodies, and investigated Leishmania DNA by real time PCR in blood and/or lymph node of each dog. The prevalence of disease was equal to 27% with 95% CI [21%; 32%], lower than prevalence obtained in the other Sicily islands (Lampedusa, Lipari). We observed that enlarged lymph nodes was more positively associated with canine leishmaniasis (CanL)than other clinical signs. The results obtained showed that in an endemic area, such as Sicily, diagnosis of CanL needs to be carried out by including an immunological, molecular clinical approach.

National health surveys linked to vital statistics and health care information provide a growing source of individual-level population health data. Pooling linked surveys across jurisdictions would create comprehensive datasets that are larger than most existing cohort studies, and that have a unique international and population perspective. This paper's objectives are to examine the feasibility of pooling linked population health surveys from three countries, facilitate the examination of health behaviours, and present useful information to assist in the planning of international population health surveillance and research studies.

The design, methodologies and content of the Canadian Community Health Survey (2003 to 2008), the United States National Health Interview Survey (2000, 2005) and the Scottish Health Survey (SHeS) (2003, 2008 to 2010) were examined for comparability and consistency. The feasibility of creating common variables for measuring smoking, alcohol consumption, physical activity and diet was assessed.
