Pierpont syndrome

What is Pierpont syndrome?

Pierpont syndrome is a rare genetic syndrome that affects multiple parts of the body. Most of the features associated with the syndrome are congenital, meaning they are present at birth. Unique facial features and limb anomalies are characteristics of the syndrome.

This syndrome is also known as:
Plantar Lipomatosis, Unusual Facies, and Developmental Delay

What gene changes cause Pierpont syndrome?

Changes to the TBL1XR1 gene are responsible for causing the syndrome.

The syndrome is inherited in an autosomal dominant pattern.

What are the main symptoms of Pierpont syndrome?

The main facial features of the syndrome include a very small head, a small jaw, widely spaced eyes, a prominent forehead, deeply set eyes, crossed eyes, a broad nasal tip, short nose, full cheeks, large and fleshy ears, and a short neck.

Physical features of the syndrome include short digits (fingers and toes), short and broad palms and a short stature.

Intellectual disability and developmental delay are also symptoms of the syndrome. Specifically, speech and language delay which is common with the syndrome.

Other symptoms of the syndrome include reduced muscle tone, seizures, scoliosis (abnormal curving of the spine), feeding issues, a failure to thrive and reduced weight.

How is it diagnosed?

To find out if someone has a diagnosis of Pierpont 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.
