Common genetic variants explain less variation in complex phenotypes than inferred from family-based studies, and there is a debate on the source of this ‘missing heritability’. We investigated the contribution of rare genetic variants to tobacco use with whole-genome sequences from up to 26,257 unrelated individuals of European ancestries and 11,743 individuals of African ancestries. Across four smoking traits, single-nucleotide-polymorphism-based heritability (\(h^2_{\mathrm{SNP}}\)) was estimated from 0.13 to 0.28 (s.e., 0.10–0.13) in European ancestries, with 35–74% of it attributable to rare variants with minor allele frequencies between 0.01% and 1%. These heritability estimates are 1.5–4 times higher than past estimates based on common variants alone and accounted for 60% to 100% of our pedigree-based estimates of narrow-sense heritability (\(h^2_{\mathrm{ped}}\), 0.18–0.34). In the African ancestry samples, \(h^2_{\mathrm{SNP}}\) was estimated from 0.03 to 0.33 (s.e., 0.09–0.14) across the four smoking traits. These results suggest that rare variants are important contributors to the heritability of smoking.

罕见的基因变异解释了吸烟遗传性缺失的原因



与基于家庭的研究推断的相比,常见的遗传变异对复杂表型的变异解释较少,并且对于这种“缺失的遗传性”的来源存在争议。我们利用多达 26,257 名无关欧洲血统个体和 11,743 名非洲血统个体的全基因组序列调查了罕见遗传变异对烟草使用的影响。在四种吸烟特征中,欧洲血统中基于单核苷酸多态性的遗传力 ( \(h^2_{\mathrm{SNP}}\) ) 估计为 0.13 至 0.28 (se, 0.10–0.13),其中 35–74其中 % 归因于较小等位基因频率在 0.01% 至 1% 之间的罕见变异。这些遗传力估计值比过去仅基于常见变异的估计值高出 1.5–4 倍,占我们基于谱系的狭义遗传力估计值的 60% 到 100% ( \(h^2_{\mathrm{ped}}\ ) ,0.18–0.34)。在非洲血统样本中,四种吸烟特征的\(h^2_{\mathrm{SNP}}\)估计为 0.03 到 0.33 (se, 0.09–0.14)。这些结果表明,罕见变异是吸烟遗传性的重要贡献者。
