Christa Lese Martin, PhD, FACMG

The pace of technology used in identifying genomic variants (changes in DNA) has been increasing at a rapid rate, and the career of Christa Lese Martin has been swept along with the improving technology. Martin’s postdoctoral training at the University of Chicago began by using Giemsa banding, or G-banding, to look at abnormalities in chromosomes. G-banding is a method that gives each chromosome a unique banding pattern and allows differences from what is normal to be detected. Newer technologies using DNA-based probes, called chromosomal microarrays, that Martin helped develop,  allowed researchers to look along the length of every chromosome for abnormalities, much like G-banding, but at a much higher resolution; a significant percentage of abnormalities could be detected that were not detectable by G-banding. As Martin says, “This rapid evolution was where my interest in technology development began, and we wanted to discover better ways to continue to identify these chromosome abnormalities from a research and clinical perspective.”

Chromosomal microarrays have allowed researchers such as Martin to identify many new genomic variants and syndromes. Consequently, Martin has worked towards the development of a clinical genomics database to share information on these genomic variants and help inform better clinical care. This project stems from her work (in conjunction with David Ledbetter, PhD, Geisinger’s Chief Scientific Officer) with the International Standards for Cytogenomic Arrays (ISCA) Consortium. They launched a project to create a database for clinical and research purposes that collects CNV data in a de-identified way, but that encourages uniformity in terms of interpreting results across different clinical laboratories. This database is particularly significant for researchers and clinicians working with patients who have rare CNVs; these single cases often don’t make it into the scientific literature, so this database allows clinicians and researchers to share data they might not otherwise have known about. NIH has developed a new database, ClinVar, based on this original CNV database, which now includes other types of DNA sequence variants. As Martin describes it, “Our ultimate goal is to improve data sharing among laboratories and clinicians to guide clinical interpretation of genomic variation–something that is becoming a part of medical practice every day.” In 2014, Martin, along with other researchers, launched GenomeConnect to enable patients to contribute their data to this database and engage them in the data sharing process.
