In recent years, statistical studies show that cholelithiasis is detected in every fifth woman and tenth man. Сholelithiasis a multifactorial process influenced by both environmental genetic factors. Some evidence suggests total plasma homocysteine correlates with the presence of gallstones, suggesting hyperhomocysteinemia risk factor for cholelithiasis. The aim this work was to analyze association polymorphic variants methylenetetrahydrofolate reductase MTHFR (rs1801133 (677C>T),...

Background and objective — Gastric cancer (GC) is one of the most common cancers worldwide with a high mortality rate. Hereditary predisposition to GC still not fully understood. The this study was compare prevalence mutations in BRCA1 (c.68_69delAG, c.4035delA, c.5266dupC, c.3700_3704delGTAAA, c.3756_3759delGTCT, c.181T>G, c.1961delA), BRCA2 (c.5946delT), CHEK2 (c.1100delC, c.115+1G>A) NBS1 (c.657_661delGTTTT) genes patients healthy donors from Volga-Ural region Russia.

Abstract Human mitochondrial DNA haplogroup U is among the initial maternal founders in Southwest Asia and Europe one that best indicates matrilineal genetic continuity between late Pleistocene hunter-gatherer groups present-day populations of Europe. While most subclades are older than 30 thousand years, comparatively recent coalescence time extant variation U7 (~16–19 years ago) suggests its current distribution consequence more dispersal events, despite wide geographical range across...

Abstract We set out to identify the origins of Árpád Dynasty based on genome sequencing DNA derived from skeletal remains Hungarian King Béla III (1172–1196) and eight additional individuals (six males, two females) originally interred at Royal Basilica Székesfehérvár. Y-chromosome analysis established that individuals, HU52 assign haplogroups R-Z2125 whose distribution centres near South Central Asia with subsidiary expansions in regions modern Iran, Volga Ural region Caucasus.

Abstract Medieval era encounters of nomadic groups the Eurasian Steppe and largely sedentary East Europeans had a variety demographic cultural consequences. Amongst these outcomes was emergence Lipka Tatars—a Slavic-speaking Sunni-Muslim minority residing in modern Belarus, Lithuania Poland, whose ancestors arrived territories via several migration waves, mainly from Golden Horde. Our results show that Belarusian Tatars share substantial part their gene pool with as indicated by...

Gastric cancer (GC) is one of the most common types in world with a high mortality rate. Hereditary predisposition for GC not fully elucidated so far. The aim this study was identification possible new candidate genes, associated increased risk gastric development.

Introduction. The geographical feature of the Volga-Ural region is its location on border Europe and Asia, which, together with proximity to Caspian steppes, Ciscaucasia Siberia, facilitated as formation many migration trade routes connecting these regions in different historical periods, which turn affected ethnogenesis peoples region.

The Early Iron Age nomadic Scythians have been described as a confederation of tribes different origins, based on ancient DNA evidence. It is still unclear how much the Scythian dominance in Eurasian Steppe was due to movements people and reflected cultural diffusion elite dominance. We present new whole-genome sequences 31 Western Eastern individuals including well samples pre- postdating them, allowing us set temporal context (in Western/Ponto-Caspian Steppe). detect an increase eastern...

Анализ геномных данных (~ 907 750 аутосомных SNP) позволил оценить уровень инбридинга на основе идентификации регионов высокой гомозиготности (FROH) в выборке из 518 человек 23 коренных народов Дагестана. В результате, популяциях коренного населения Дагестана количество и суммарная длина ROH, а также коэффициент FROH показывают значительное разнообразие как внутри, так между исследованными популяциями. У гинухцев, гунзибцев, ахвахцев, бежтинцев цезов наблюдаются одни самых высоких значений...
