The grant information from the National Institutes of Health should read: This work is supported by National Institutes of Health grant R01GM088566 and R01ES016626.
In the original publication, a critical reference regarding the methods and simulation setup employed in our research was omitted. The additional reference is:
Lin D, Feng R, Chen J (2010) Maximum Likelihood Methods for Assessing Genetic Imprinting Using Case-Control Mother-Child Pair Data. Manuscript.
This work should be cited in the following Sections:
-Section 3 (Likelihood), page 3, 1st column, line 2 from the bottom, cite this reference and it should read as “…the parent of origin of the allele at the testing locus (Lin et al., 2010).”
-Section 7 (Simulations) first paragraph, page 4, 2nd column, cite Lin et al. (2010) at the end of the 2rd sentence. It should read as “…on the power of the haplotype-based method (Lin et al., 2010).”
-Section 7 (Simulations), page 4, 3rd paragraph, 1st sentence, add “following a similar simulation setup as in Lin et al. (2010)” before “we generated the genotypes…”
-Page 8, 1st column, line 8, add “A similar power gain by incorporating the haplotype information was also observed in Lin et al. (2010) in case-control mother-child pairs.”
