Description: A genome-wide parent-of-origin linkage study for obesity (BMI, body mass index, waist circumference)
was carried out in European American (1,297 individuals from 260 families), German (370 from 89
families) and African American samples (277 from 52 samples). For quantitive trait analysis a
maternal effect was observed at 12q24, with a single point LOD score of 2.85 and a multipoint score
of 4.01 for body-mass-index and 3.69 for waist circumference (Dong
C et al, 2005).
