^aFor BMI, the total sample size shown is 658. The number is greater than the 630 subjects genotyped, because markers of 28 subjects could not be amplified (usually as a result of poor quality or degradation of the DNA) or because our archive contained only phenotype data. However, because the genotypes of these 28 subjects can often be unambiguously inferred from their relatives, their phenotype data are useful in linkage analyses. Therefore, their phenotype data are also included in the summary for the above table.
