Association of some SNP in TGFA,IRF6 and nonsyndromic cleft lip with or without cleft palate by DNA microarray technology / 中华检验医学杂志

ABSTRACT

Objective To explore the relationship between some single nucleotide polymorphisms (SNP)loci of interferon regulatory factor 6(IRF6)gene,transforming growth faetor-?(TGFA)gene and nonsyndromic cleft lip with or without cleft palate(NSCL/P)in nuclear families consisting of fathers, mothers and affected offspring with NSCL/P from southeast China.Methods Some SNloci of IRF6 and TGFA were detected by applying microarray technology in nuclear families,and then haplotype relative risk (HRR)and transmission disequilibrium test(TDT)were performed.Results There were no significant difference in genotypes and alleles distribution between patients and their parents.The SNP locus——V274I of IRF6 was associated with NSCL/P(HRR?~2=4.5816,P
