Background: Efficient treatment of inherited hyperphenyl-alaninemia requires exact identification of mutations defining the trait. Such knowledge is important both for effective individual therapy and understanding of the genetic history and evolution of regional populations.
Methods: DNA sequencing of amplified genome regions was used to identify mutations.
Results: Hyperphenylalaninemia-associated mutations in the phenylalanine hydroxylase locus were identified for 76 unrelated patients from the Novosibirsk region, Russia and for their family members. Twenty-one mutation types were identified, most of them rare and one (IVS2+1delG) not previously described. Common for European populations, the mutation p.R408W appeared to be the most frequent, with allele frequency 63.33%. We also looked for mutations in the quinoid dihydropteridine reductase locus in some patients. For 36 unrelated children PKU patients with known blood phenylalanine levels, we tried to find correlations between this level and the genotype.
Conclusions: Comparative analysis revealed correlations between blood phenylalanine levels and genotypes. The spectrum of phenylalanine hydroxylase mutations in the Novosibirsk region population appeared to be rather complex, probably as a result of mixed ethnic composition, formed by several multidirectional migration flows.

Background: The antioxidant activity of estrogen has a be ne - ficial impact in Alzheimer’s disease. A variety of clinical stu - dies have demonstrated that estrogen replacement therapy in postmenopausal women results in a lower frequency of AD, delaying the onset of the neurodegenerative cascade. On the other hand, it has been demonstrated that estrogens may exhibit genotoxic effects, especially at elevated tissue concentrations. Therefore, the aim of this study was to determine whether b-estradiol induces DNA damage in the peripheral blood lymphocytes of healthy young females and males, healthy elderly females and males and females and males with Alzheimer’s disease.
Methods: All experiments were performed using the alkaline version of the Comet assay (single cell gel electrophoresis), on six donors per each experimental group and controls.
Results: In the Comet assay, a significant increase of DNA migration was observed in the lymphocytes of all treated groups (young and elderly females, young and elderly males, AD females and AD males) at all b-estradiol concentrations (50 mmol/L, 100 mmol/L and 250 mmol/L) used in this investigation. In all the experiments cell viability was over 80%.
Conclusions: Lymphocytes are sensitive to the test concentrations of b-estradiol in the Comet assay regardless of gender, age and health condition of the examined subjects. Therefore, the role of b-estradiol in cellular DNA damage has been confirmed.

Background: Coronary artery disease (CAD) is a complex trait influenced by genetic and environmental factors. Geographic isolation and natural selection present fundamental forces to diversify genetic backgrounds during human evolution and migration. In this study, we attempted to assess whether human geographic isolation affects the genetic predisposition of CAD.
Methods: We first included 21 genetic association studies of the methyl enetetrahydrofolate reductase (MTHFR) gene polymorphism C677T and CAD from 16 geographic regions consisting of 9,008 participants and performed a meta-ana - lysis based on the distributions of these studies.
ResultsIt was found that the positive signals for the association of C677T with CAD were mainly enriched in the regions of northern Afri ca (pooled OR=1.73, 95% CI=1.45-2.06, Z=3.17, P<0.0001) and India (pooled OR=1.61, 95% CI=1.30- 2.00, Z=4.38, P<0.0001). To validate the potential geographic effects on the genetic polymorphism of CAD, we then carried out two additional metaanalyses involving 30 and 13 studies on genetic associations of the angiotensin-converting enzyme (ACE) gene insertion/ deletion (I/D) and APOA5 gene T1131C polymorphisms for CAD consisting of 22,190 and 12,322 participants, respectively. We found that the associations of T1131C with CAD were concentrated in East Asia (pooled OR=1.35, 95% CI=1.22-1.49, Z=6.00, P<10-5), whereas the associations of I/D polymorphism with CAD were clustering in Europe and America (pooled OR=1.20, 95% CI=1.04-1.39, Z=2.49, P=0.01) and Turkey (pooled OR=1.33, 95% CI=1.05-1.69, Z=2.40, P=0.02).
Conclusions: Our results showed that geographic isolation might have potential effects on the genetic polymorphism of human complex diseases, such as CAD.
