Um yes. I have one and there is all kinds of increased risks with having one. Infertility, miscarriage, ectopic pregnancy, placenta previa, placental abruption, placental accretia, IUGR, fetal anomalies - often with the limbs, breech presentations - often not cut and dry, malposition, premature rupture of membranes, premature birth and uterine rupture (even if you have never been cut before).
Mullerian anomalies occur in the beginning stages of fetal development. They can occur for a variety of reasons. Sometimes there is a genetic compononent, sometimes not. It could just be random or caused by something ingested by the mother during pregnancy or enviromental.
There is a yahoo support group for Mullerian Anomalies, excellent resource for information.
