Increased levels of DNA methyltransferases in the placentas of women affected by Placenta Accreta Spectrum lead to aberrant DNA methylation patterns.

Placenta Accreta Spectrum (PAS) is a serious placental abnormality assosiated with significant maternal death during pregnancy. Due to its invasive characteristics resembling tumor growth, PAS is often associated with tumor-related proteins. While DNA methylation is known to regulate genes involved in development, its potential role in the development of PAS remains unclear.
