What is Craniosynostosis, Adelaide Type (CRSA)?

Craniosynostosis itself is a condition, present at birth, whereby the bones of a baby’s skull fused together prematurely before the brain has fully developed. This in turn leads to a skull that is abnormally shaped as the brain grows.

It is closely linked to Saethre-chotzen syndrome and Pfeiffer syndrome.

What gene change causes Craniosynostosis, Adelaide Type (CRSA)?

There is no definitive gene yet identified as known to be causing the syndrome.

It is inherited in an autosomal dominant pattern.

What are the main symptoms of Craniosynostosis, Adelaide Type(CRSA)?

  • Hallux valgus- an abnormality concerning the joint of the big toe. It can lead to arthritis.
  • Abnormalities of the carpal bones located in the wrist.
  • Abnormalities of the fingers and fingernails.
  • Abnormalities in the bones of the feet.
  • Craniosynostosis- where the skull bones of a baby join together too early creating skull abnormalities.

Possible clinical traits/features:
Carpal bone malsegmentation, Craniosynostosis, Cone-shaped epiphyses of the phalanges of the hand, Cone-shaped epiphyses of the toes, Shortening of all middle phalanges of the fingers, Shortening of all distal phalanges of the fingers, Hallux valgus.

How is it diagnosed?

To find out if someone has a diagnosis of Craniosynostosis, Adelaide type (CRSA), 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.
