摘要

Aims: The present study was performed to determine whether there are variants in TBX20 and genes of the Ras-MAPK pathway associated with nonsyndromic congenital heart disease (ns-CHD). @@@ Materials and Methods: A total of 223 ns-CHD patients and 273 healthy controls from China were selected as study subjects to perform an association analysis using 22 tag single-nucleotide polymorphisms (tag SNPs) located either in one of three genes in the Ras-MAPK pathway (MAP2K2, BRAF, and RAF1) or the TBX20 gene that have previously been associated with syndromic congenital heart disease. @@@ Results: The results showed that none of these tag SNPs are associated with ns-CHD. @@@ Conclusions: The results suggested that these disease-causing genes, which were previously discovered in familial cases, might not be the major genetic factors causing the development of ns-CHD in Chinese.
