Which are the symptoms of Marden Walker Syndrome?

Marden-Walker syndrome, also known as MWS or Marden-Walker-like syndrome, is a rare genetic disorder that primarily affects the development of the musculoskeletal and nervous systems. It is characterized by a distinct combination of physical and intellectual disabilities, which can vary in severity from person to person.

Physical Symptoms:

Individuals with Marden-Walker syndrome often exhibit a range of physical symptoms, including:

• Joint contractures: This is one of the hallmark features of MWS. Joint contractures refer to the limited range of motion in the joints, particularly in the elbows, knees, and hips. These contractures can lead to a characteristic "pigeon-like" stance.


• Facial anomalies: Facial features may include a small mouth, a high-arched palate, a small chin, and a flat nasal bridge.


• Eye abnormalities: Some individuals with MWS may have ptosis (droopy eyelids), strabismus (crossed or misaligned eyes), or other eye abnormalities.


• Low muscle tone: Hypotonia, or decreased muscle tone, is common in individuals with MWS. This can affect their ability to sit, stand, or walk independently.


• Growth abnormalities: Growth may be stunted, resulting in short stature or failure to thrive in some cases.


• Respiratory problems: Breathing difficulties, such as recurrent respiratory infections or a weak respiratory system, can occur in individuals with MWS.

Intellectual and Developmental Symptoms:

Marden-Walker syndrome is also associated with various intellectual and developmental challenges, including:

• Intellectual disability: Most individuals with MWS have some degree of intellectual disability, ranging from mild to severe.


• Delayed development: Children with MWS may experience delays in reaching developmental milestones, such as sitting, crawling, or walking.


• Speech and language difficulties: Communication can be affected, with delayed speech development and difficulties with articulation.


• Learning disabilities: Some individuals with MWS may have specific learning difficulties, such as problems with reading, writing, or math.


• Behavioral issues: Behavioral problems, including hyperactivity, impulsivity, and self-injurious behaviors, may be present in some individuals with MWS.


• Seizures: Epileptic seizures can occur in a subset of individuals with MWS.

Other Features:

In addition to the primary symptoms mentioned above, individuals with Marden-Walker syndrome may also exhibit other features, such as:

• Cardiac abnormalities: Some individuals may have structural heart defects or other cardiac issues.


• Genitourinary anomalies: Certain individuals may have abnormalities in the urinary or genital systems.


• Skeletal abnormalities: Bone deformities, such as scoliosis or joint abnormalities, may be present in some cases.


• Visual and hearing impairments: Vision and hearing problems can occur in individuals with MWS.

It is important to note that the symptoms and their severity can vary widely among individuals with Marden-Walker syndrome. Therefore, it is crucial to consult with a healthcare professional for an accurate diagnosis and appropriate management of the condition.
