What is Cold-Induced Sweating Syndrome?

This rare disease is a genetic condition characterized by excessive sweating, affecting mainly the chest, face, arms, and trunk of the body, brought on by a cold or ambient temperature.

What gene change causes Cold-Induced Sweating syndrome?

Mutations in the CRLF1 and CLCF1 genes are responsible for the syndrome. It is inherited in an autosomal recessive pattern.

Autosomal recessive inheritance means an affected individual receives one copy of a mutated gene from each of their parents, giving them two copies of a mutated gene. Parents, who carry only one copy of the gene mutation will not generally show any symptoms but have a 25% chance of passing the copies of the gene mutations onto each of their children.

What are the main symptoms of Cold-Induced Sweating syndrome?

  • One of the main identifying symptoms of the condition is profuse sweating in cold temperatures. Individuals may also experience extreme sensitivity to pain and cold temperatures.
  • Other features of the syndrome include a high-arched palate, nasal voice, a depressed nasal bridge, a broad nose, a long philtrum, and a large face with full cheeks.
  • Seizures and hypotonia (low muscle tone) are also reasonably common symptoms of the syndrome.
  • Sometimes symptoms associated with the syndrome may be more severe, including feeding difficulties in infancy, and sudden cardiac death.

How is Cold-Induced Sweating syndrome diagnosed?

To find out if someone has a diagnosis of Cold-Induced Sweating syndrome, it is important to have a consultation and evaluation with a clinical genetic specialist.  Specialists may also suggest specific genetic testing or other types of tests to help reach a diagnosis.  FDNA’s AI technology can help speed up the diagnostic process by analyzing facial features and other health information.

Yunis-Varon syndrome (YVS)

It is a rare genetic disease that affects multiple systems of the body. Its main symptoms affect the skeletal and nervous systems, as well as ectodermal tissue (hair and teeth). Since 1980 just 25 cases from 19 families have been diagnosed and recorded. This syndrome is also known as: Cleidocranial Dysplasia With Micrognathia, Absent Thumbs, And Distal Aphalangia

Xia-Gibbs syndrome (XIGIS)

It is a rare genetic syndrome associated mainly with intellectual disability. This syndrome is also known as: Mental Retardation, Autosomal Dominant 25; Mrd25 Changes in the AHDC1 gene are responsible for causing the syndrome. It is inherited in an autosomal dominant pattern, although all cases of the syndrome recorded so far have been the result of de novo or new mutations in the gene. In the case of autosomal dominant inheritance just one parent is the carrier of the gene mutation, and they have a 50% chance of passing it onto each of their children. Syndromes inherited in an autosomal dominant inheritance are caused by just one copy of the gene mutation. In some cases, a genetic syndrome may be the result of a de-novo mutation and the first case in a family. In this case, this is a new gene mutation which occurs during the reproductive process.
