conclusions the current meta-analysis showed an association between frequency of gg genotype of pnpla3 and the risk of development of chc in various populations throughout the world. results five hospital-based case-control studies were included in the final analysis. the overall frequency of pnpla3 gene polymorphisms was 20.4% (205/1005) in chc and 10.23% (53/518) in controls. the summary odds...

AIM To find an association between Y chromosome polymorphisms and some ethnic groups. METHODS Short tandem repeats (STR) and single-nucleotide polymorphisms (SNP) on the Y chromosome were typed in 311 unrelated men from four different ethnic groups - Italians from northern Italy, Albanians, Africans from the Maghreb region, and Indo-Pakistanis, using the AmpFlSTR® Yfiler PCR Amplification Kit...

We investigated Y chromosomal binary and STR polymorphisms in 263 unrelated male individuals from the Japanese population and further examined the relationships between the two separate types of data. Using 47 biallelic markers we distinguished 20 haplogroups, four of which (D2b1/-022457, O3/-002611*, O3/-LINE1 del, and O3/-021354*) were newly defined in this study. Most haplogroups in the Japa...

Human Y-chromosomal DNA analysis is becoming well established in forensic sciences. That is because human Y-chromosomal DNA polymorphisms are the only genetic markers that are able to specifically characterize and identify male culprit DNA in material from sexual assault or forcible rape cases where offenders are almost always males. Appropriate Y-chromosomal DNA markers evaluated for forensic ...

The DAZ gene, a contributing factor in infertility, lies on the human Y chromosome's AZFc region, whose deletion is a common cause of spermatogenic failure. Y chromosome binary polymorphisms on the non-recombining Y (NRY) region, believed to be a single occurrence on an evolutionary scale, were typed in a sample of fertile and infertile men with known DAZ backgrounds. The Y single-nucleotide po...

In this paper, we present a study of genetic variation in sub-Saharan Africa, which is based on published and unpublished data on fast-evolving (hypervariable region 1 of mitochondrial DNA and six microsatellites of Y chromosome) and slow-evolving (haplogroup frequencies) polymorphisms of mtDNA and Y chromosome. Our study reveals a striking difference in the genetic structure of food-producer (...

The individual response to diet may be influenced by gene polymorphisms. This study hypothesized that ADRB2 (Gln27Glu, rs1042714 and Arg16Gly, rs1042713), ADRB3 (Trp64Arg, rs4994) and GHRL (Leu72Met, rs696217) polymorphisms moderate weight loss. The study was a seven weeks dietary weight loss intervention with Brazilian adult obese women (n = 109). The body mass index (BMI) was calculated and p...

A multiplex PCR assay capable of amplifying 20 Y-chromosome short tandem repeat (STR) markers simultaneously has been developed. These markers include all of the Y STRs that make up the ‘‘extended haplotype’’ used in Europe (DYS19, DYS385, DYS389I/II, DYS390, DYS391, DYS392, DYS393, and YCAII) plus additional polymorphic Y STRs (DYS437, DYS438, DYS439, DYS447, DYS448, DYS388, DYS426, GATA A7.1,...
