The authors of the above-listed article have requested the following erratum.

In this study we describe the replication of a QTL at 3q27 for BMI in two independent African-American family samples. After publication, we determined that the family ID was labeled incorrectly in the lab for a subset of participants in the second sample. As a result, 64 families were genotyped in both samples 1 and 2. We subsequently removed those families from sample 2 and genotyped an additional 57 families. Sample 2 now comprises 466 individuals in 121 families. We genotyped nine STRs evenly spaced in the 43-cM (one marker/5 cM) region around the peak on 3q27 identified in our previous study. Multipoint linkage analysis by Genehunter software gave the maximum LOD score of 3.05 at map position 176 cM, ∼10 cM from the peak identified in sample 1. Next, we carried out linkage analysis within the 43-cM region combining samples 1 and 2. Because sample 2 has more markers than sample 1 in the region, we first calculated the IBD sharing of a pair of relatives in samples 1 and 2 separately. The IBD probabilities were then pooled for linkage analysis. Linkage evidence was increased in the combined sample to an MLS of 3.7 at 188 cM, with a 17-cM 1-LOD drop interval around the peak (Fig. 1). We used the same methods as described in the article, and the results of our analyses did not change significantly.
