Causes of Costello syndrome

Costello syndrome is caused by a change, or mutation, in a specific gene called HRAS. This gene gives instructions for making a protein that helps cells grow and divide properly. When there is a mutation in the HRAS gene, it can lead to cells dividing too quickly and in an uncontrolled manner, causing the symptoms associated with Costello syndrome. This mutation usually occurs randomly, and it is not inherited from parents.

The HRAS gene mutation in Costello syndrome affects many different systems in the body, including the skin, heart, muscles, and bones. This can result in a wide range of symptoms such as intellectual disability, heart defects, short stature, and distinctive facial features. The complex interactions between these different systems and the effects of the HRAS gene mutation contribute to the overall impact of Costello syndrome on an individual's health and development.

Who is affected by it

In addition to the physical symptoms, Costello syndrome can also have a significant impact on the emotional and social well-being of individuals and their families. Managing the complex medical needs associated with Costello syndrome can be challenging, and may require the support of a multidisciplinary team of healthcare professionals. Friends, family members, and caregivers of those with Costello syndrome may also be affected by the emotional and financial demands of caring for a loved one with this condition.

Types of Costello syndrome

Costello syndrome has two main types: HRAS mutation-positive Costello syndrome and HRAS mutation-negative Costello syndrome.

HRAS mutation-positive Costello syndrome is caused by a change in a specific gene called HRAS, which leads to the characteristic features of the syndrome. Individuals with this type may experience developmental delays, intellectual disability, heart abnormalities, and distinctive facial features such as large lips, broad forehead, and a wide nasal bridge.

On the other hand, HRAS mutation-negative Costello syndrome is diagnosed when an individual shows symptoms of the syndrome but does not have mutations in the HRAS gene. This type can present similar features to the positive type, but the underlying genetic cause may be different. Both types of Costello syndrome require careful monitoring and management to address the various medical and developmental challenges that can arise.

Diagnostic of Costello syndrome

Costello syndrome is a rare genetic disorder that can be diagnosed through a combination of physical examination, medical history, and genetic testing.
