The Authors would like to apologize for an analytical issue that led to a couple minor errors in this article.

On page 1848, 5th line of 1st paragraph in the left column “ … these five SNPs explained 4.59% of the … ” should be “ … these five SNPs explained 6.33% of the … ”

Footnote e for Table 2: “r2 was calculated as model sum of squares divided by corrected total sum of squares” should be “r2 was calculated as model sum of squares divided by error sum of squares”.

On page 1853, 13th line of 2nd paragraph in the section of Statistical analysis: “divided by the corrected total sum of squares of the full model” should be “divided by the error sum of squares of the model without the SNP(s)”.

The conclusions and major findings are not affected by these errors.
