Early Diagnostic Markers in Crisponi Syndrome: Two Cases and Review.

ABSTRACT: Background: Crisponi/cold-induced sweating syndrome (CS/CISS) is a rare autosomal recessive disorder characterized by severe neonatal manifestations including paroxysmal muscle contractions, tendency for hyperthermia, and feeding and swallowing difficulties with high neonatal mortality. Pathogenic variants in the Cytokine Receptor-Like Factor 1 (CRLF1) gene have been associated with CS/CISS. These variants result in a loss of function of the encoded protein, which disrupts the formation of a functional heterodimer with Cardiotrophin-Like Cytokine Factor 1 (CLCF1). This complex is essential for the development of autonomic and sensory nervous systems, as well as for bone remodeling. We report two patients affected by CS harboring pathogenic variants in the CRLF1 gene. <
