Stephen Chanock

Stephen Jacob Chanock (born April 15, 1956) is an American physician and geneticist.

He has held multiple positions, both in research and scientific leadership over his career at the NCI.

[1] He has received numerous awards for his work in the discovery and characterization of cancer susceptibility regions in the human genome.

Chanock co-leads several international consortial studies to identify and characterize the genetics of cancer susceptibility including BRCA Challenge, Game-On, and the NCI Cohort Consortium.

His work focuses specifically on efforts to clarify the genetic architecture of cancer susceptibility,[2][3] the scope of genetic mosaicism and its contribution to cancer risk,[4][5] and how germline variation informs our understanding of somatic alterations in cancer[6][7] and investigation of how ionizing radiation causes thyroid cancer in children exposed to the Chornobyl accident and the lack of evidence for a transgenerational effect in cleanup workers following the Chornobyl accident.
