encodes a UDP-galactose transporter essential for glycosylation of proteins and galactosylation of lipids and glycosaminoglycans. Germline genetic variants have been identified in congenital disorders of glycosylation and somatic variants have been linked to intractable epilepsy associated with malformations of cortical development. However, the functional consequences of these pathogenic variants on brain development and network integrity remain elusive.

Background: Electrocardiograms (EKGs) are routinely performed in pregnant patients with pre-existing cardiovascular disease. However, in pregnant patients with congenital heart disease (CHD), EKG changes during gestation have not been explored.
Methods: We performed a retrospective study of pregnant patients with CHD enrolled in the STORCC initiative.

Background: Epidemiological studies report associations of drinking water disinfection byproducts (DBPs) with adverse health outcomes, including birth defects. Here, we used a rat model susceptible to pregnancy loss (full-litter resorption; FLR) and eye malformations (anophthalmia, microphthalmia) to test 11 DBPs, including trihalomethanes, haloacetic acids (HAAs), and nitrogen-containing DBPs (N-DBPs).
Methods: Timed-pregnant F344 rats received gavage doses of chloroform, chlorodibromomethane, iodoform, chloroacetic acid, bromoacetic acid, dibromoacetic acid (DBA), diiodoacetic acid (DIA), trichloroacetic acid (TCA), dibromonitromethane, and iodoacetonitrile on gestation days (GD) 6-10.

Background: Neural tube defects (NTDs) are defined as an incomplete closure of the neural tube (NT), with a prevalence of 1.2 per 1000 live births around the world. Methylation of the maternally imprinted gene Insulin-like growth factor 2 (IGF2) is one of the epigenetic mechanisms that contribute significantly to the development of NTDs.

SUMOylation involves covalent attachment of small ubiquitin-like modifier (SUMO) proteins to specific lysine residues on target proteins and regulates various aspects of their function. Sentrin-specific proteases (SENPs) are key players in both the conjugation reaction of SUMO proteins to their targets and the subsequent deconjugation of SUMO-conjugated substrates. Here, we provide the first comprehensive prenatal description of a lethal syndrome linked to a novel homozygous stop-gain variant in SENP7 c.
