We additionally observed a variant 126 kb downstream of the transcription start site of SCG2 associated with risk of PN at genome-wide significance in the entire cohort: rs115575220 (G/T with T being the risk allele, p = 4.15 × 10−8, HR = 2.44, 95% CI = 1.77–3.35, risk allele frequency = 0.012). The gene discussed is SCG2; the disease is poikiloderma with neutropenia.
