Management of Maternal Genetic Conditions in Pregnancy, Part 1: Disorders of the Connective Tissue, Muscle, Vascular, and Skeletal Systems.

Importance: The number of patients with various genetic syndromes who are or seek to become pregnant is increasing due to advances in medical care and assisted reproductive technologies. Management of these patients requires multidisciplinary care teams and knowledge of the risks of increased morbidity and mortality. In addition, many of these inheritance patterns are autosomal dominant, with a 50% risk of an offspring inheriting the disorder with each pregnancy.

Objectives: In this first of a 2-part series, common syndromes with connective tissue, muscle, vascular, or skeletal involvement will be discussed regarding surveillance and management of mother and fetus.

Evidence acquisition: A literature search was performed for important updates in the literature regarding management of patients with genetic connective tissue disorders, aortopathies, muscular dystrophies, vascular disorders, and skeletal dysplasias.

Results: Updates have been incorporated since the last publication in 2011, including updated diagnostic criteria for several conditions (such as Marfan syndrome), international guidelines in management of aortopathies and achondroplasia, an expanded section on hypermobile Ehlers-Danlos syndrome, and a new section on familial cerebral cavernous malformation.

Conclusions: Since the last publication, many guidelines have been published or updated regarding management of pregnancies in patients with genetic disorders and are reviewed in this article.

Relevance: Clinicians who care for pregnant patients with genetic disorders should be aware of updated guidelines and recommendations in order to optimize their care during pregnancy.
