Technique Insights

The market is divided into comparative genomic hybridization, FISH, immunohistochemistry, karyotyping, and others. The comparative genomic hybridization segment owns the highest market share. Comparative Genomic Hybridization (CGH) is a molecular biology method employed to examine and contrast the genetic material of two distinct DNA samples, usually one derived from a test sample (such as a tumor cell) and the other from a reference sample (such as normal tissue). The main objective of CGH is to detect chromosomal abnormalities, such as amplifications or deletions of genetic material, in the test sample compared to the reference sample.

In addition, CGH has been extensively employed in cancer research to detect chromosomal aberrations linked to the initiation and advancement of tumors. Genomic profiling is a highly effective method for comprehensively investigating genetic changes at a global level. It has played a fundamental role in identifying genetic markers and elucidating the molecular mechanisms underlying different disorders, such as cancer.

Application Insights

The market is divided into genetic disorders, oncology, personalized medicine, and other applications. The oncology segment dominates the market over the forecast period. Molecular cytogenetics is essential for comprehending the genetic changes linked to cancer. It aids in identifying translocations, a process in which genetic material is swapped between two chromosomes. For instance, the Philadelphia chromosome results from a translocation event involving chromosomes 9 and 22. It is frequently observed in cases of chronic myeloid leukemia (CML). Molecular cytogenetic techniques can also identify deletions (loss of genetic material) and duplications (additional copies of genetic material), frequently observed in different cancers. Thus, molecular cytogenetics is widely used in oncology for cancer diagnosis.
