Maternal genetic diseases: potential concerns for mother and baby.

With advances in medical care, many women with genetic conditions previously known to decrease life expectancy are reaching childbearing age. Thus, it is important to understand the management of patients in the preconception, antepartum, and postpartum periods as they pose a unique challenge to the obstetrician. Most rare disorders lack well-established clinical guidelines for management in pregnancy. Existing data stem from case reports, case series, and expert opinion. We aim to summarize these recommendations and develop a clinical reference for managing reproductive age women with these conditions. We review recommendations for women with inborn errors in metabolism, connective tissue disorders, skeletal dysplasia, and selected single gene disorders. In all cases, it is crucial to employ a multidisciplinary team to optimize care for patients with rare disease before, during, and immediately after their pregnancies. The emphasis on expert consensus recommendations in the guidance of obstetric care is a signal that more studies are needed to determine best practices. [ABSTRACT FROM AUTHOR]
