摘要
Deiodinase enzyme II (DIO2) has an important role in individuals' thyroid hormones' level, the development of central and peripheral nervous systems and characterized by mental retardation (MR). The DIO2 gene was genotyped by using five haplotype-tagging single-nucleotide polymorphisms (SNPs) in 157 Chinese MR high-density family pedigrees, including 452 nuclear families and >1460 persons. The single marker and haplotype analyses were performed by Family-based Association Tests (FBAT). Three SNPs had P-values <0.05 in at least one inherited model survived with the correction. Several haplotypes composed of these SNPs were also associated with MR. The in silico analyses identified that one of the SNPs, rs1388378, may be a functional SNP. However, further in vitro studies of this SNP should be considered in elucidating its effect on gene expression and the possible role in MR susceptibility.
