Trisomy 21 or Down syndrome (DS) is the most frequent genetic etiology of intellectual disability in humans. MDM2 gene expression has a potential role as a risk factor for human aneuploidy. -410T-G (rs2279744) functional polymorphism in MDM2 gene impacts on the mechanisms of chromosomal non-disjunction. We analyzed, within a case-control study, such polymorphism in mothers of subjects with DS. Nucleotide polymorphism was detected by pyrosequencing technology. The distribution of MDM2-410T-G polymorphism showed no significant difference among mothers of subjects with DS and controls. Our results suggest that MDM2 -410T-G polymorphism is not a risk factor for DS in mothers.
