Mutations in WNT4 are not responsible for Müllerian duct abnormalities in Chinese women

摘要

The WNT4 gene plays a crucial role in sexual differentiation and female genital tract development. This study screened WNT4 for mutation in 189 Chinese women with Müllerian duct abnormalities (10 Mayer-Rokitansky-Küster- Hauser syndrome, five Müllerian aplasia and 174 incomplete Müllerian fusion) and detected no perturbation that would indicate a major role for WNT4. Only one novel synonymous mutation (c.1091G > A) in exon 5 and one known single-nucleotide polymorphism (rs16826648) in exon 2 were found. The results suggest that WNT4 might not contribute to the aetiology of Müllerian duct abnormalities in Chinese women.
