We sought to determine whether individuals who later develop thyroid cancer more frequently have CH before diagnosis or germline cancer susceptibility than healthy controls.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>METHODS<\/jats:title>\n            <jats:p>We conducted a retrospective case-control study using subjects enrolled between 2002 and 2015 in a population-based biobank. Cases were healthy at enrollment but subsequently developed an incident thyroid cancer. Controls were healthy age- and race-matched subjects who were never diagnosed with a cancer. To assess baseline CH, whole-exome sequencing (WES) was performed on peripheral blood (PB) DNAs collected at enrollment. To assess CH acquisition over time, we recontacted a subset of cases and controls approximately 20 years after initial sampling for repeat PB WES.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>RESULTS<\/jats:title>\n            <jats:p>\n              At enrollment, on average 9 years before a thyroid cancer diagnosis for cases, we identified CH in three of 63 (5%) cases and four of 125 (3%) controls. Adjusting for age, sex, and race, those with CH had a 1.51 odds (0.31-7.33;\n              <jats:italic toggle=\"yes\">P<\/jats:italic>\n              = .61) of a thyroid cancer diagnosis versus those without CH at baseline.

Among seven cases and seven controls recontacted, we found incident CH development in three (43%) and two (29%), respectively.\n            <\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>CONCLUSION<\/jats:title>\n            <jats:p>We found that individuals who later develop early-stage thyroid cancers do not have a significantly higher prevalence of CH years before their diagnosis nor carry germline cancer susceptibility variants more often than those who do not develop thyroid cancer.
