Crisponi/cold-induced sweating syndrome is an autosomal recessive disorder characterized in the neonatal period by orofacial weakness with impaired sucking and swallowing resulting in poor feeding necessitating medical intervention. Affected infants show a tendency to startle, with contractions of the facial muscles in response to tactile stimuli or during crying, trismus, abundant salivation, and opisthotonus. During the first year, most infants have spiking fevers. These features, referred to as 'Crisponi syndrome' in infancy, can result in early death without advanced care. After the first 2 years, the abnormal muscle contractions and fevers abate, and most patients show normal psychomotor development. From childhood onward, the most disabling symptoms stem from impaired thermoregulation and disabling abnormal sweating, which can be treated with clonidine. Patients have hyperhidrosis, mainly of the upper body, in response to cold temperatures, and sweat very little with heat. Other features include characteristic facial anomalies, such as round face, chubby cheeks, micrognathia, high-arched palate, low-set ears, and depressed nasal bridge, dental decay, camptodactyly, and progressive kyphoscoliosis (summary by Hahn et al., 2010). Buers et al. (2020) provided a detailed review of Crisponi/CISS, including clinical features, diagnosis, and evolution of the disease, differential diagnosis, pathogenesis, and recommended management and treatment. Genetic Heterogeneity of Crisponi/Cold-Induced Sweating Syndrome Crisponi/cold-induced sweating syndrome-2 (CISS2; 610313), which is clinically indistinguishable from CISS1, is caused by mutation in the CLCF1 gene (607672) on chromosome 11q13.  http://www.omim.org/entry/272430

Many of the health problems associated with Crisponi syndrome improve with time, and affected individuals who survive the newborn period go on to develop other features of cold-induced sweating syndrome in early childhood. Within the first decade of life, affected individuals begin having episodes of profuse sweating (hyperhidrosis) and shivering involving the face, torso, and arms. The excessive sweating is usually triggered by exposure to temperatures below about 65 or 70 degrees Fahrenheit, but it can also be triggered by nervousness or eating sugary foods. Paradoxically, affected individuals tend not to sweat in warmer conditions, instead becoming flushed and overheated in hot environments.

Adolescents with cold-induced sweating syndrome typically develop abnormal side-to-side and front-to-back curvature of the spine (scoliosis and kyphosis, often called kyphoscoliosis when they occur together). Although infants may develop life-threatening fevers, affected individuals who survive infancy have a normal life expectancy.

Infants with Crisponi syndrome have unusual facial features, including a flat nasal bridge, upturned nostrils, a long space between the nose and upper lip (philtrum), a high arched roof of the mouth (palate), a small chin (micrognathia), and low-set ears. The muscles in the lower part of the face are weak, leading to severe feeding difficulties, excessive drooling, and breathing problems. Other physical abnormalities associated with Crisponi syndrome include a scaly skin rash, an inability to fully extend the elbows, overlapping fingers and tightly fisted hands, and malformations of the feet and toes. Affected infants startle easily and often tense their facial muscles into a grimace-like expression. By six months of age, infants with Crisponi syndrome develop unexplained high fevers that increase the risk of seizures and sudden death.

Cold-induced sweating syndrome is characterized by problems with regulating body temperature and other abnormalities affecting many parts of the body. In infancy, the features of this condition are often known as Crisponi syndrome. Researchers originally thought that cold-induced sweating syndrome and Crisponi syndrome were separate disorders, but it is now widely believed that they represent the same condition at different times during life.  https://medlineplus.gov/genetics/condition/cold-induced-sweating-syndrome
