Genetic Diagnosis and Clinical Features of Fetuses With Congenital Diaphragmatic Hernia

Prenatal Diagnosis, EarlyView.
ABSTRACT Objective Congenital diaphragmatic hernia (CDH) is a rare abnormality with highly heterogeneous genetic causes. This study investigated chromosomal and monogenic abnormalities in fetal CDH patients and evaluated the efficacy of chromosomal microarray analysis (CMA) and whole‐exome sequencing (WES) for genetic diagnosis.

Prenatal Exome Sequencing Identifies Dual Maternal‐Fetal Diagnosis of HbF Mission Bay, a Novel HBG2 Variant Associated With Methemoglobinemia, Hypoxia and Hemolytic Anemia

Prenatal Diagnosis, EarlyView.
ABSTRACT Prenatal exome sequencing (ES) can establish rare genetic diagnoses in a fetus but may also lead to occult genetic diagnosis in a biological parent. We present a case of dual fetal and maternal diagnosis by prenatal ES, in a fetus with unexplained anemia and in a pregnant patient with sickle cell disease (SCD) and recurrent unexplained hypoxia.

Screening Positive for Rare Autosomal Aneuploidies Increases Frequency of Adverse Pregnancy Outcomes and Alters Clinical Management

Prenatal Diagnosis, EarlyView.
ABSTRACT Objective Outcomes in pregnancies with rare autosomal aneuploidies (RAAs) are poorly characterized, with most studies having small sample sizes. Here, we describe outcomes and management in a large cohort of pregnancies that screened positive for an RAA (RAA+).
