It showed that fewer actionable genetic changes \u2013 those that can be targeted for treatment \u2013 were identified in those from non-European backgrounds. Whole genome sequencing was not able to find treatment-relevant findings for 26% of participants of South Asian ancestry compared with 16% of European ancestry.\u00a0<\/p>\n<p>One possible explanation for this put forward by the research team is that limited genetic research involving diverse populations means genetic changes commonly found in non-Europeans are less studied. This makes it more difficult to separate truly harmful gene changes from the harmless ones.\u00a0<\/p>\n<p>Some gene changes running in families can increase the risk of getting cancer, such as the BRCA1 gene.\u00a0 Identifying people who are more susceptible to developing certain types of cancer makes it easier to prevent or diagnose the condition earlier, which is vital to improving patient outcomes.\u00a0The study tested the capabilities of the genomics pipelines used in England to find those changes for people of different ancestries. While the pipelines demonstrated a strong ability to do this, people of non-European ancestry background had more of these changes flagged \u2013 although some were unlikely to be linked to cancer as they were common genetic changes among these groups.\u00a0<\/p>\n<p>The study is the first to examine the role of ancestry within genetic screening and targeted treatment within a national cancer sequencing programme.\u00a0\u00a0<\/p>\n","protected":false},"excerpt":{"rendered":"Greater diversity is needed in genetic research to make genomics\u2019 use in cancer care and screening more accurate&hellip;\n","protected":false},"author":2,"featured_media":178032,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[3846],"tags":[267,70,16,15],"class_list":{"0":"post-178031","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-genetics","8":"tag-genetics","9":"tag-science","10":"tag-uk","11":"tag-united-kingdom"},"share_on_mastodon":{"url":"https:\/\/pubeurope.com\/@uk\/114669666043369535","error":""},"_links":{"self":[{"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/posts\/178031","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=178031"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/posts\/178031\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/media\/178032"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/media?parent=178031"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/categories?post=178031"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/tags?post=178031"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
