Polymorphic deletions of the phase I and phase II genes involved in the detoxification of potential carcinogens may be a risk factor for nasopharyngeal carcinoma. In this study, we investigated the relationship between <i>CYP2E1<\/i> (rs3813867), <i>CYP2A6, GSTM1<\/i>(rs1183423000) and <i>GSTT1<\/i>(rs1601993659) gene variations and NPC risk in North African countries with the highest incidence of NPC (Morocco, Algeria and Tunisia). and the evaluation of the potential use of these variants as potential biomarkers for NPC management.<\/p>\n<h2>Methods<\/h2>\n<p>A total of 600 NPC cases and 545 controls frequency-matched on ethnicity, sex, age and childhood household type, were recruited from three North African countries (Morocco, Algeria and Tunisia) and analysed. Genotyping of <i>CYP2A6<\/i> and <i>CYP2E1<\/i>(rs3813867) was performed by polymerase chain reaction restriction (PCR)-fragment length polymorphism (RFLP) analysis and the <i>GSTM1<\/i> (rs1183423000) and <i>GSTT1<\/i>(rs1601993659) genetic variations were evaluated using the PCR technique.<\/p>\n<h2>Results<\/h2>\n<p>The genotype distributions of <i>CYP2E1<\/i>(rs3813867)<i>, CYP2A6, GSTM1<\/i>(rs1183423000) and <i>GSTT1<\/i>(rs1601993659) genotypes did not differ significantly among NPC cases and controls (<i>p<\/i>\u00a0&gt;\u00a00.05). Furthermore, our data did not reveal any association with smoking and the studied variants, even when the samples were stratified by the duration period of smoking.<\/p>\n<h2>Conclusion<\/h2>\n<p>In this large studied North African population, our findings suggest that the functional <i>CYP2E1<\/i>, <i>CYP2A6, GSTM1<\/i> and <i>GSTT1<\/i> variations did not influence NPC susceptibility.<\/p>","protected":false},"excerpt":{"rendered":"<p>Annals of Human Genetics, EarlyView.<\/p>\n","protected":false},"author":0,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[60,6,42],"tags":[43],"class_list":["post-910","post","type-post","status-publish","format-standard","hentry","category-annals-of-human-genetics","category-articulos","category-original-article","tag-annhumgenet"],"_links":{"self":[{"href":"https:\/\/sebigec.es\/blog\/index.php\/wp-json\/wp\/v2\/posts\/910","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/sebigec.es\/blog\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/sebigec.es\/blog\/index.php\/wp-json\/wp\/v2\/types\/post"}],"replies":[{"embeddable":true,"href":"https:\/\/sebigec.es\/blog\/index.php\/wp-json\/wp\/v2\/comments?post=910"}],"version-history":[{"count":1,"href":"https:\/\/sebigec.es\/blog\/index.php\/wp-json\/wp\/v2\/posts\/910\/revisions"}],"predecessor-version":[{"id":911,"href":"https:\/\/sebigec.es\/blog\/index.php\/wp-json\/wp\/v2\/posts\/910\/revisions\/911"}],"wp:attachment":[{"href":"https:\/\/sebigec.es\/blog\/index.php\/wp-json\/wp\/v2\/media?parent=910"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/sebigec.es\/blog\/index.php\/wp-json\/wp\/v2\/categories?post=910"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/sebigec.es\/blog\/index.php\/wp-json\/wp\/v2\/tags?post=910"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
