With the aim to dissect the eect of adult height on head and neck cancer (HNC), we use the Mendelian
randomization (MR) approach to test the association between genetic instruments for height and
the risk of HNC. 599 single nucleotide polymorphisms (SNPs) were identied as genetic instruments
for height, accounting for 16% of the phenotypic variation. Genetic data concerning HNC cases
and controls were obtained from a genome-wide association study. Summary statistics for genetic
association were used in complementary MR approaches: the weighted genetic risk score (GRS) and the
inverse-variance weighted (IVW). MR-Egger regression was used for sensitivity analysis and pleiotropy
evaluation. From the GRS analysis, one standard deviation (SD) higher height (6.9 cm; due to genetic
predisposition across 599 SNPs) raised the risk for HNC (Odds ratio (OR), 1.14; 95% Condence Interval
(95%CI), 0.99–1.32). The association analyses with potential confounders revealed that the GRS was
