Alport syndrome (AS) is a progressive renal disease characterized by hematuria and progressive renal failure. X-linked dominant AS (XLAS) is the major inheritance form, accounting for almost 80% of the cases, caused by mutations in COL4A5 gene. An accurate genetic diagnosis of AS is very important for genetic counseling and even prenatal diagnosis. In this study we detected mutation of COL4A5 by amplifying the entire coding sequence mRNA of peripheral blood lymphocytes using nested PCR in a Chinese XLAS family, and then performed the first prenatal diagnosis of AS in China. Mutation analysis of the fetus was performed on both cDNA-based level and DNA-based level of amniocytes. Fetus sex was determined by PCR amplification of SRY and karyotypes analysis. Maternal cell contamination was excluded by linkage analysis. There was a G-to-A substitution at position 4,271 in exon 46 of COL4A5 gene (c.G4271A) in the pregnant woman; this genetic variant has not been described previously and was a novel missense mutation. The fetus did not carry the same mutation as the mother. PCR amplification product of SRY and karyotypes analysis revealed a male fetus. Linkage analysis showed that there was no contamination of maternal cells in amniocytes.
