We wish to report some corrections to our study [1], none of which alters the interpretation of the data or the conclusions drawn. After publication of this work we noted that the sample size required further clarification.

Results

A total of 246 infants (114 cases, 132 controls; 116 males, 121 females, 9 with imputed gender) passed laboratory quality control. Statistical quality control removed 15 individuals for low genotyping, resulting in a total of 231 individuals (103 cases, 128 controls; 114 males, 117 females). Of the 655,352 SNPs tested, 68,297 failed statistical quality control due to HWE P < 0.001 in the controls (N = 431), low genotyping rate (N = 21,589), or for MAF < 0.01 (N = 53,477), where some overlap of SNPs across exclusion criteria existed. Results were presented for 587,055 SNPs.
