Fig. 1: Miami plot of meta-analysis for age at voice breaking.

Miami plot comparing –log10(P values) for SNP associations with age at voice breaking from 23andMe GWAS (bottom half, blue shades) with –log10(P values) from meta-analysis for age at voice breaking combining 23andMe data with UK Biobank study (top half, red shades). Red line indicates genome-wide significance level (P < 5 × 10−8).
