Clinical Genomic Variant Curator: Rare Disease Group

This position is an opportunity to play a critical role in the development of large resources to improve the understanding of the function and disease impact of human genetic variants. The Broad Institute is accumulating data sets of genetic variation of unprecedented scale, covering a wide range of human ancestries, technologies, and disease areas, and spanning hundreds of thousands of people. This role would involve work on the Genome Aggregation Database (gnomAD;, the world’s largest reference database of sequenced humans, led by Daniel MacArthur, and on the Broad’s Center for Mendelian Genomics, an NIH-funded collaborative venture focused on discovering new disease genes, and the Rare Genomes Project (, a direct-to-patient genome sequencing initiative providing diagnoses to rare disease families across the US, both co-led by Heidi Rehm and Daniel MacArthur. Our mission is to create open resources for scientists and clinicians, and to use these resources to improve rare disease diagnosis, discover new disease genes, understand the functional impact of genetic variation, and empower the basic and clinical genomics community worldwide.

We are searching for an enthusiastic variant curator to research and classify genetic variants identified through gnomAD and our rare disease genomics efforts. This will involve using ClinGen’s variant curation tool, as well as other third party tools, and internally-developed software to determine a variant’s pathogenicity.
