Application of Genomic Ancestry in finding Cancer prone Population Boosting Genomics Market

Posted On December 31, 2020     

Experience and constant research by many experts have shown that several disparities are present in cancer if one looks at a patient’s race and ethnicity. It has been seen that some particular ethnic and racial populations experience a greater occurrence of specific cancers as compared to people of other ethnic and racial backgrounds. The problem faced is that genomic causes of disparities are a subject that is poorly understood in most types of cancers. This issue is further augmented due to the lack of data that is available on the topic.

Genetic ancestry imitates the history of human migration; it offers background information about genetic variations that is critical to associate diseases genetically. A recent study took up the challenge of examining genomic ancestry in BCL subtypes, which would be exciting progress for the Genomics Market.

 The researchers proceeded with their examination by applying genomic ancestry prediction methodology. This method helped in obtaining comprehensive genomic profiling of data. As a result, they found several genomic differences.
BCL (B-cell Lymphoma and Leukemia) is an assorted set of malignancies. Many researchers have emphasized the BCL subtypes' genomic landscape, but its genomic ancestry has seldom been explored.

The team analyzed DNA (Deoxyribonucleic acid) and RNA (Ribonucleic acid) alterations from BCL samples taken from unique patients and tried to obtain information on genomic ancestry classes. They found that patients with B-cell acute lymphoblastic leukemia (ALL) were enriched with American (AMR) ancestry (reflecting Latin American and Hispanic population).

The research comprised of RNA and DNA variations analyses in 2,834 unique patient BCL samples, which is done to obtain information on genomic ancestry classes. The research concluded that enrichment of American (AMR) ancestry (reflecting Hispanic and Latin American population) was present in patients with B-cell acute lymphoblastic leukemia (ALL).

Patients with Leukemia were found to be enriched with the high-risk Philadelphia chromosomes like ALL. They also had a greater frequency of JAK2, IGH, IKZF1, IL7R, and CRLF2 gene mutations.

DLBCL (Diffuse large B cell lymphoma) was primarily found to be of European ancestry, but the team also identified several genomic ancestry differences. These include CDKN2A, which was frequently altered in East Asian ancestry, and  CD79B alterations were enriched in patients of South Asian ancestry.  Similarly, EZH2 alterations were a little bit enriched in American ancestry; and CUX1 (a tumor suppressor involved in PI3K signaling) was strongly enriched in African ancestry for both B-cell ALL and DLBCL.

This study identified multiple genomic differences in BCL malignancies by using genomic ancestry instead of patient-reported explanatory variables. This research may lead to new insights that will show why some cancers occur more frequently in specific populations. Moreover, it can help identify better strategies for early diagnosis, targeted treatments, and disease prevention.
