A team of scientists led by Prof. Solomon Rotimi of the Department of Biochemistry, Covenant University, Ota, Ogun State has successfully conducted the first-ever entirely local study as it affects how specific genetic factors like BRCA1 and BRCA2 are driving breast cancer among Nigerian women.\n<\/p>\n
The lead researcher, Rotimi, was equally said to have documented this breakthrough in a journal titled \u2018Screening of Germline BRCA1 and BRCA2 Variants in Nigerian Breast Cancer Patients,\u2019 and published in the Technology in Cancer Research and Treatment journal.\n<\/p>\n
The university disclosed this in a statement on Friday.\n<\/p>\n
It explained that, though, studies on genes like BRCA1 and BRCA2, which are known to increase the risk of breast and ovarian cancer, had been extensively carried out in Western populations \u2013 but far less so in African populations \u2013 and where such studies have been done in Nigeria, they relied heavily on foreign expertise.<\/p>\n
The university said that although having a family history of cancer disease and genetic factors are well-established risks, very little is known about the specific genetic factors driving breast cancer in Nigerian women.\n<\/p>\n
The statement said, \u201cOur team at Covenant University bridged this gap by publishing a first-of-its-kind, entirely local study in Nigeria to understand how changes (called \u201cvariants\u201d) in the BRCA1 and BRCA2 genes may contribute to breast cancer among Nigerian women.\n<\/p>\n
\u201cIn doing this, Professor Rotimi\u2019s team used advanced technology (DNA sequencing) to examine both genes in the blood.<\/p>\n
\u201cThey conducted all the laboratory work \u2014 from DNA extraction to sequencing and data analysis \u2014locally at Covenant University\u2019s Cancer Genomics Laboratory, which is under the Covenant Applied Informatics and Communication Center of Excellence (CApIC- ACE). <\/p>\n
\u201cThe following are the important findings of this study: About 7% of breast cancer patients had harmful changes in BRCA1 or BRCA2 genes.\n<\/p>\n
\u201cThese were found only in women with triple-negative breast cancer who also had a family history of cancer. It is important to note that these genes can be passed on to children.\n<\/p>\n
\u201cThese harmful variants were not found in healthy women. We discovered unique BRCA gene patterns (called haplotypes) that are distinct in Nigerian women \u2014 patterns that are rarely or never seen in other populations.\n<\/p>\n
According to the statement, the team also found many other BRCA variants that, while not harmful on their own, may play a role in cancer risk when combined with other factors.\n<\/p>\n
\u201cThis study matters for controlling the cancer burden because it is a milestone for African science, as it clearly demonstrates our capacity to conduct complex cancer genomics investigations independently, without us tying to the apron of the Western countries.\n<\/p>\n
\u201cAlso, it reveals that some Nigerian women may carry unique genetic markers for breast cancer that are not seen in Western population.<\/p>\n
\u201cThe findings support the call for population-specific genetic testing and early screening tools tailored for Nigerian women that can help in early identification of women who are at higher risk of breast or ovarian cancer.\n<\/p>\n
\u201cIt\u2019s important to note that it opens the door to genetic counselling and more personalised treatment option,s which are particularly effective for BRCA-related breast cancers,\u201d the statement added.\n <\/p>\n","protected":false},"excerpt":{"rendered":"A team of scientists led by Prof. Solomon Rotimi of the Department of Biochemistry, Covenant University, Ota, Ogun…\n","protected":false},"author":2,"featured_media":32651,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[3846],"tags":[1378,19231,267,70,19232,16,15],"class_list":{"0":"post-32650","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-genetics","8":"tag-breast-cancer","9":"tag-covenant-university","10":"tag-genetics","11":"tag-science","12":"tag-solomon-rotimi","13":"tag-uk","14":"tag-united-kingdom"},"share_on_mastodon":{"url":"https:\/\/pubeurope.com\/@uk\/114364070656363773","error":""},"_links":{"self":[{"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/posts\/32650","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/comments?post=32650"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/posts\/32650\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/media\/32651"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/media?parent=32650"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/categories?post=32650"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/tags?post=32650"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
