New-Onset Type 1 Diabetes in a Child with Joubert Syndrome: A Rare Endocrine Complication.

Joubert syndrome (OMIM #213300) is a rare predominantly autosomal recessive inherited condition characterized by the classic cerebellar vermis hypoplasia and brainstem anomalies (also known as the "molar tooth sign"), hypotonia, and developmental delays. Joubert syndrome is a ciliopathy that affects multiple systems including the central nervous system, eyes, kidneys, liver, respiratory, musculoskeletal system, cardiovascular system, and endocrine system. Endocrine abnormalities are not uncommon in Joubert syndrome, such as growth hormone deficiency, thyroid hormone deficiency, central diabetes insipidus, hypopituitarism, micropenis, and obesity.

Unexplained Progressive Respiratory Insufficiency and Weakness Diagnosed as Late-Onset Pompe Disease Through Biochemical and Molecular Genetic Testing.

Late-onset Pompe disease is a rare autosomal recessive lysosomal storage disorder caused by acid α-glucosidase deficiency, resulting in progressive skeletal muscle weakness and respiratory failure. We present the case of a 43-year-old African American woman who was admitted to the intensive care unit with acute-on-chronic hypoxemic and hypercarbic respiratory failure, alteration of consciousness, and progressive weakness. Her recent medical history included respiratory distress and aspiration pneumonia, which had not fully resolved despite supplemental oxygen therapy.

The D409H variant in GBA1: Challenges in predicting the Gaucher phenotype in the newborn screening era.

Gaucher disease (GD) is an autosomal recessive disorder resulting from glucocerebrosidase deficiency due to pathologic variants in GBA1. While clinically heterogeneous, GD encompasses three types, non-neuronopathic (GD1), acute neuronopathic (GD2), and chronic neuronopathic (GD3). Newborn screening (NBS), which has made remarkable inroads in detecting certain diseases before detrimental health consequences and fatality ensues, is now being piloted for GD in several states and countries.
