To study the association between transforming growth factor alpha gene (TGFalpha) TaqI variant and nonsyndromic cleft lip with or without cleft palate (nsCL/P) in Chinese population.
TGFalpha TaqI variant was detected using polymerase chain reaction-restriction fragment length polymorphism for DNA samples of the 149 triads with nsCL/P affected child. We performed the Transmission/disequilibrium test and the family-based association study (FBAT) to identify the associations between this variant and risk of nsCL/P.
Significant distortion of C2 allele at TGFalpha TaqI locus in nsCL/P groups (P > 0.05) was not found. In the family-based association test, C2 allele and offspring C2C1 genotype was not found to be significantly associated with an increase risk of nsCL/P (P > 0.05).
Our findings did not suggest an association between offspring TGFalpha TaqI variant and the increased risk of nsCL/P in Chinese population.
研究转化生长因子α基因（TGFα）TaqI 变异与中国人群非综合征性唇裂伴或不伴腭裂（nsCL/P）之间的关联。
采用聚合酶链反应-限制性片段长度多态性方法，对 149 例有 nsCL/P 患病子女的三联体的 DNA 样本进行 TGFα TaqI 变异检测。我们进行传递/不平衡检验和基于家系的关联研究（FBAT），以确定该变异与 nsCL/P 风险之间的关联。
未发现 nsCL/P 组中 TGFα TaqI 位点的 C2 等位基因有显著畸变（P > 0.05）。在基于家系的关联检验中，未发现 C2 等位基因和子代 C2C1 基因型与 nsCL/P 风险增加有显著关联（P > 0.05）。
我们的研究结果未表明子代 TGFα TaqI 变异与中国人群中 nsCL/P 风险增加之间存在关联。
