Toriello-Carey syndrome comprises agenesis of the corpus callosum, telecanthus, small palpebral fissures, Pierre Robin sequence, abnormal ears, and cardiac defects. We report a boy who has some additional findings, including a severe respiratory failure and intestinal dysmotility. The boy died of these two disorders at age 13 months. Histological examination revealed pulmonary immaturity and a defect of smooth muscle cells in the longitudinal muscle coat of the intestinal musculature, both of which might explain some aspects of the pathophysiology of the patient.

A Novel Pathogenic Variant in the Gene in a Patient Presenting with Rhombencephalosynapsis and Craniofacial Anomalies, Expanding MN1 C-terminal Truncation Syndrome.

Meningioma-1 is a transcription activator that regulates mammalian palate development and is required for appropriate osteoblast proliferation, motility, differentiation, and function. Microdeletions involving the gene have been linked to syndromes including craniofacial anomalies, such as Toriello-Carey syndrome. Recently, truncating variants in the C-terminal portion of the MN1 transcriptional factor have been linked to a characteristic and distinct phenotype presenting with craniofacial anomalies and partial rhombencephalosynapsis, a rare brain malformation characterized by midline fusion of the cerebellar hemispheres with partial or complete loss of the cerebellar vermis.

Article Synopsis
- The study investigates a large group of 411 patients from 288 families with skeletal dysplasia, focusing on their genetic information.
- It finds 224 potentially harmful genetic variations in 123 related genes, including five that may be significant for the disease, and identifies both established and new phenotypic categories of skeletal dysplasia.
- The research highlights a higher-than-average disease burden in their population and aims to enhance the diagnosis of skeletal dysplasia by broadening our understanding of its phenotypic and genetic diversity.
Proximal Deletion of 6q Overlapping with Toriello-Carey Facial Phenotype: Prenatal Findings, Clinical Course, Differential Diagnosis, and Review.

Proximal deletion of 6q is a relatively rare chromosomal abnormality. Reported patients have deletions of different sizes but share partial overlap and present with similar clinical features, and some of them were described prior to the introduction of chromosome microarrays. We describe a male patient with prenatal sonographic findings of nuchal edema, intrauterine growth restriction, renal pelvis dilatation, and oligohydramnios.

Recently, de novo heterozygous variants in DDX3X have been reported in about 1.5% of 2659 females with previously unexplained intellectual disability (ID). We report on the identification of DDX3X variants in two unrelated girls with clinical features of Toriello-Carey Syndrome (T-CS).
