Interplay Between the Exposome and the Genome in Health and Disease
A recent review assessed the interplay between environmental exposures and the human genome and showed ways that this interplay can alter disease risk. Many diseases, such as birth defects and developmental disabilities, type 2 diabetes and cancer, are influenced by both environmental and genetic factors. The cumulative effects of environmental exposures prenatally and throughout life Read More >

Rapid advances in human genome sequencing technologies have accelerated the integration of genomics into clinical practice. Genomics has demonstrated clinical utility as a diagnostic tool for certain diseases, but its potential for population screening is still work in progress. In principle, DNA-based population screening can identify persons with rare pathogenic variants who are at high Read More >

A 2021 report by the African Academy of Sciences (AAS), the Alliance for Accelerating Excellence in Science in Africa (AESA), and the African Union Development Agency (AUDA-NEPAD) presented a framework for the implementation of genomic medicine for public health in Africa. Globally, there is widespread recognition of the potential of genomic medicine (GM) to improve Read More >

Despite years of public health efforts, family health history remains underutilized in clinical care, especially among people who are medically underserved. To address these issues, CDC’s Office of Genomics and Precision Public Health hosted a webinar on November 14, 2022, in conjunction with National Family Health History Day (Thanksgiving). The speakers called for better informed, Read More >

Since the completion of the Human Genome Project, major advances have occurred in the translation of human genome discoveries into clinical practice and disease prevention. As almost all human diseases are due to complex gene-environment interactions, the applications of human genomics should be pertinent to the prevention and control of many diseases, including rare and Read More >

A recent review outlines the use of circulating tumor DNA (ctDNA) in clinical practice and the requirements necessary to extend the use of this technology for health impact. Cell-free DNA (cfDNA) is extracellular strands of DNA present in body fluids. Circulating tumor DNA (ctDNA) is a specific type of cfDNA that originates from a primary tumor, circulating Read More >

In 1997, in response to the Human Genome Project, the CDC formed the Office of Genetics and Disease Prevention, now called the Office of Genomics and Precision Public Health (OGPPH). This was the beginning of the public health genomics movement in the United States and around the world. Our office continues to serve CDC programs, Read More >

A recent study identified a cell free RNA (cfRNA) signature that was promising in predicting pre-eclampsia several weeks before the onset of symptoms. At 29 weeks pregnant, Erica was diagnosed with preeclampsia, a pregnancy complication marked by high blood pressure and signs of organ failure, most often liver or kidney damage. According to the Mayo Read More >

“The number of possible ‘causal’ [gene-environment] interactions is so enormous that every patient’s disease likely has its own complex and unique cause. This uniqueness limits predictive ability: it is impossible to accurately predict something that has never occurred before.” Cecile Janssens, DNA tells great stories—about the past, not future, WIRED, December 5, 2013 Risk prediction Read More >

A September 2022 publication recommended that every European country should have a Familial Hypercholesterolemia program for early detection screening, diagnosis, and care. Familial Hypercholesterolemia (FH) is a genetic condition that results in elevated levels of low-density lipoprotein cholesterol (LDL-C) from birth, resulting in increased risk of heart disease and myocardial infarction. A 2021 blog from Read More >
