Rapp-Hodgkin Syndrome (RHS)

What is Rapp-Hodgkin syndrome?

Rapp-Hodgkin is a rare genetic syndrome that is also a form of ectodermal dysplasia. There are around 150 conditions within the group of ectodermal dysplasia syndromes that present with similar symptoms. The syndrome mainly affects the skin, hair, nails, teeth, and sweat glands of affected individuals.

This syndrome is also known as:
Ectodermal Dysplasia, Anhidrotic, with Cleft Lip/palate RHS

What gene changes cause Rapp-Hodgkin syndrome?

Changes in the TP63 gene cause the syndrome.

It is inherited in an autosomal dominant pattern.

What are the main symptoms of Rapp-Hodgkin syndrome?

  • The syndrome is characterized by symptoms that affect the skin, hair, nails, teeth, and sweat glands of affected individuals.
  • These signs include thinning, brittle hair, often accompanied by hair loss (alopecia). Many individuals experience little to no ability to sweat, along with heightened sensitivity to heat.
  • Issues affecting the teeth include absent teeth, cone-shaped incisors, and enamel that is thin or absent.
  • Individuals affected also have misshapen or absent nails on their fingers and toes.

How is it diagnosed?

To find out if someone has a diagnosis of Rapp-Hodgkin 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.

Weiss-Kruszka syndrome (WSKA)

It is a multiple congenital anomaly syndrome that has been recently identified. There are just 24 potential cases currently reported worldwide. It is also known as Weiss-Kruska syndrome. The gene responsible for the disorder is the ZNF462 gene.

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.
