*Genotyped for 1100delC which was observed in 2.01% (3/149) of cases vs 0.7% (1/141) controls. If we compare the frequency in cases with that seen in the same neonatal controls used in this study, that were also tested for 1100delC by Zhang et al [30] (19 1100delC carriers among 6460 controls), then the difference between cases and controls is statistically significant (P = 0.01).
