Rethinking eGFR Across Populations: Insights from GATM Genetics and Metabolomics
In this webinar, Dr. Olivia Gray, Senior Scientist at Variant Bio, presents a multi-omic investigation into the glycine amidinotransferase (GATM) locus, a key regulator of endogenous creatine biosynthesis. By integrating whole-genome sequencing, deep renal phenotyping, and metabolomic profiling, her team demonstrates that common African-enriched GATM variants can systematically lower eGFR estimates derived from creatinine without impacting true kidney function.
Attendees will learn how metabolomics was critical in uncovering the biological mechanism linking these variants to elevated circulating creatine and downstream creatinine levels, as well as how these findings help explain potential misclassification of CKD risk in African ancestry populations. This work highlights the importance of incorporating genetic and metabolic context into clinical biomarker interpretation to enable more accurate and equitable precision medicine.
