Cytogenomics primarily focuses on structural variability within chromosomes. Understanding chromosome variations through cytogenetic analysis is an integral part of current genomic medicine, playing a role in both constitutional disorders and cancer.
Traditional molecular cytogenomic methods for assessing chromosomal abnormalities, including FISH and karyotyping, enable visualization of the genome, but often at low resolution. Data generated from these cytogenetic analysis methods tend to be inconsistent and highly dependent upon the user’s skills. Cytogenomic microarrays offer a simpler, more reliable, unbiased method that demonstrates higher resolution for assessing chromosomal aberrations. These qualities, along with the fast and standardized cytogenetic analysis workflows, have led to the global adoption of arrays in cytogenomic studies. Next-generation sequencing (NGS) technologies offer detection capabilities even beyond that of arrays.
Illumina is committed to assisting the cytogenomic community in the pursuit of accurate, reproducible chromosome aberration data for constitutional disorders and cancer. For this reason, Illumina acquired BlueGnome, a well-known provider of cytogenetic analysis solutions. Our goal is to offer a cytogenomics product portfolio that provides greater insight into chromosomal aberrations and their biological relevance.
