Described associations between PPARG polymorphisms and breast carcinoma are also discrepant: some researchers see a marginally significant increase in the risk of breast cancer among women homozygous for the Ala allele of PPAR γ (Pro12Ala), causing a reduction in the transcriptional activity of PPAR γ 2 [ 35 ], while others stress that carriers of the same variant allele are at lower risk [ 36 ].
