Our results suggest that significant oxidative stress exists in Hodgkin lymphomas, both in RS cells and in reactive cellular infiltrates. Mitochondrial antioxidant enzymes are induced in the most aggressive forms of the disease, and they may play some part in chemoresistance.
Objective
To investigate the applicability of carrier screening in women undergoing invasive prenatal diagnosis.
Design
Prospective study.
Setting
University‐based clinic.
Participants
Two hundred and fifty‐six pregnant women.
Methods
Gene tests were offered for fragile X syndrome, aspartylglycosaminuria and infantile neuronal ceroid lipofuscinosis at the time of invasive prenatal testing.
Results
The overall uptake of the tests was 92%. Previously unrecognised carriership was found in 10 women: aspartylglycosaminuria (7); infantile neuronal ceroid lipofuscinosis (2) and fragile X (1). Fetal genotyping was carried out in one carrier of aspartylglycosaminuria whose partner was also a carrier, and in one woman who was found to have fragile X premutation. Both fetuses were unaffected.
Conclusion
Carrier screening for single‐gene disorders is feasible and well accepted among pregnant women undergoing invasive prenatal testing. The major benefit is that there is no need to consider extra invasive tests when carriership is detected. Incorporation of genetic testing into fetal karyotyping gives more security to future parents.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
