Basilicata-Akhtar syndrome

What is Basilicata-Akhtar syndrome?

Basilicata-Akhtar syndrome is a rare disease that presents with global developmental delay beyond infancy, limited to zero speech, feeding issues, and low muscle tone (hypotonia). It affects males and females similarly.

This syndrome is also known as:
Basilicata-Akhtar syndrome; Intellectual development disorder, X-linked syndromic type 36.

What gene changes causes this syndrome?

Mutations in the MSL3 gene cause the syndrome.

It is inherited in an X-linked dominant pattern.

What are the main symptoms of Basilicata-Akhtar syndrome?

The main symptoms of the syndrome include global developmental delay, which extends past infancy. This also presents with limited to zero speech, and many affected individuals are able to walk but with an unstable gait. Behavioral abnormalities are also common with the syndrome, as is intellectual disability.

Unique facial features of the syndrome include a smooth philtrum, downturned corners of the mouth, deeply set eyes, low-set ears with hearing impairment in some cases, a tented upper lip, a wide nasal ridge, and a short neck.

The syndrome may also affect the limbs, with hyper flexibility in the lower limbs, and a short and broad foot in some instances.

Generalized low muscle tone (hypotonia), and progressive spasticity are also symptoms of the syndrome.

How is it diagnosed?

To find out if someone has a diagnosis of Basilicata-Akhtar 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.
