The Genome Aggregation Database (gnomAD) is a resource that collects and shares genetic information from diverse populations. It aims to provide a comprehensive view of human genetic variation by aggregating data from various studies, including whole-genome and exome sequencing. Researchers use gnomAD to understand the frequency of genetic variants and their potential links to diseases. gnomAD includes data from thousands of individuals, making it a valuable tool for scientists and clinicians. By analyzing this information, they can identify rare genetic variants and assess their significance in health and disease, ultimately aiding in personalized medicine and genetic research.
