IBD sharing around the PPARG locus is not increased in dizygotic twins or their mothers.
Busjahn et al reported finding linkage between PPARG (3p25) and being a dizygotic (DZ) twin. We differentiate, as do the authors, between the conception of DZ twins, and being the viable result of such a conception.
