The answer is both yes and no. When the mother has genetic thrombophilia, the baby's risk of obtaining some form of the condition can be either 50% or 100%, depending on whether the mother has both of the abnormal genes or only one. What is more important and least understood by most obstetricians is the fact that the mother may be healthy and yet the placenta and the fetus may suffer from genetic fetal thrombophilia, which was inherited from the father. In other words, the risk of the baby to have genetic thrombophilia as well as the severity of it depend on whether the mother, the father or both of them have some form of genetic thrombophilia. At KOFINAS PERINATAL we are very successful in identifying this condition because we pay keen attention to the placental development and not just to the maternal blood tests. On numerous occasions, we have prevented health setbacks in the extended family by advising testing of the fatherÕs lineage. When the mother has acquired thrombophilia there is no direct and absolute risk of developing this condition during fetal life. There may be a slight increase in the risk of developing the same condition in adulthood but this risk is not known.
