Precision Genetic Medicines

Beam is pioneering the use of CRISPR base editing to treat disease, one letter at a time.


The human genome is made up of billions of nucleobases, or “bases,” represented by the letters A, G, T, and C. Beam’s base editing technology can precisely target and make specific edits to a single base in DNA or RNA, without cutting or disrupting the gene. Base editors have the potential to repair disease-causing point mutations, write in protective genetic variations, or modulate the expression or function of disease-causing genes. Beam is committed to developing base editors as a new class of precision genetic medicines that can treat or cure diseases affecting patients’ lives.
