Keutel Syndrome

What is Keutel syndrome?

It is a rare genetic syndrome. It is characterized by the calcification (when calcium salts accumulate in body tissue) of cartilage in the ears, nose, throat, voice box, and ribs of those affected.

What gene change causes Keutel syndrome?

Changes in the MGP gene are responsible for causing 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 Keutel syndrome?

The calcification of cartilage in multiple parts of the body is the main symptom of the syndrome.

Other symptoms include unique facial features such as a long or elongated face, a prominent nasal bridge, a decreased midface size, a wide nose, and short fingers and toes.

Other possible symptoms include deafness, mild intellectual disability, recurrent middle ear infections, increased blood pressure in the lungs (pulmonic stenosis), and ventricular septal defect (a congenital heart anomaly).

How is Keutel syndrome diagnosed?

To find out if someone has a diagnosis of Keutel 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.
