Transplant patients may help to unlock the secrets of ctDNA

By | February 7th, 2018|Categories: ctDNA, Next-generation sequencing|0 Comments

Can transplant genomics help better understand ctDNA? Circulating cell free (cfDNA) of tumour (ctDNA) is released by apoptotic and necrotic cells into blood and other bodily fluids. It has transformed NIPT and is transforming Cancer medicine. However the biology behind it’s release is still not […]

A recent BioRxiv report from the Gerlinger group at ICR describes a targeted ctDNA sequencing method that uses error correcting UMIs to achieve 100% sensitivity for mutant allele frequencies of >0.15%, and 87% at >0.075%, and reduce false-positive mutation calls by 98.6%, without adversely affecting the […]
