Marshall syndrome

Marshall syndrome is a rare genetic disorder that affects various parts of the body, including the eyes, ears, joints, and facial structure.

Physical Characteristics

• Facial dysmorphism: Individuals with Marshall syndrome often have distinctive facial features, such as a long face, large eyes, and a small nose [1].
• Ocular involvement: The condition can cause eye problems, including high myopia (nearsightedness) and cataracts [2][3].
• Hearing loss: Early-onset hearing loss is a common symptom of Marshall syndrome [4][5].

Other Symptoms

• Skeletal anomalies: Individuals with Marshall syndrome may experience skeletal issues, such as short stature, spondyloepiphyseal dysplasia (a condition affecting the spine and joints), and early-onset osteoarthritis [6][7].
• Anhidrotic ectodermal anomalies: This condition can cause skin problems, including reduced sweating ability [8].

Inheritance Pattern

Marshall syndrome is inherited in an autosomal dominant pattern, meaning that a single copy of the mutated gene is enough to cause the condition. It affects males and females equally [9][10].

It's essential to note that Marshall syndrome is often confused with Stickler syndrome due to overlapping clinical features. However, they are distinct conditions caused by mutations in different genes [11].

Marshall syndrome is characterized by a distinctive set of signs and symptoms, which can be divided into several categories.

Facial Features

• A flat sunken midface with a flattened nasal bridge (saddle nose) [1]
• Nostrils that turn upward [4]
• Wide space between the eyes (hypertelorism) [1]
• Thicker upper portion of the skull (calvaria) with calcium deposits [4]

Eye Abnormalities

• High myopia [6]
• Cataracts [14]

Hearing Loss and Skeletal Anomalies

• Early-onset hearing loss [2, 12]
• Short stature [2, 12]
• Spondyloepiphyseal dysplasia (a type of skeletal anomaly) [12]
• Arthropathy (joint disease) [6]

Other Symptoms

• Developmental delays [7]
• Respiratory issues and infections [7]
• Failure to thrive [9]

It's worth noting that Marshall syndrome is a rare genetic disorder, and the severity and presentation of symptoms can vary from person to person.

Marshall syndrome can be diagnosed through various diagnostic tests, which may include:

• Imaging studies: These may show accelerated bone maturation or minor brain abnormalities such as hypoplasia of the corpus callosum [9].
• Genetic testing: This can help identify mutations in the COL11A1 gene that cause Marshall syndrome [2][3].
• Brain MRI: May show corpus callosum anomalies, macrogyria, pachygyria, delayed myelination, ventricular dilatation, hydrocephalus and periventricular white matter abnormalities [8].
• Blood tests: May reveal moderate leukocytosis and an elevated erythrocyte sedimentation rate [11].
• Specialist referrals: A primary care physician (PCP) can help order diagnostic tests and coordinate providers as part of a healthcare team [13][14].

It's worth noting that the diagnosis of Marshall syndrome is typically made through a combination of clinical evaluation, imaging studies, and genetic testing.

Treatment Options for Marshall Syndrome

Marshall syndrome, also known as Marshall-Smith syndrome, is a rare genetic disorder that requires comprehensive management to alleviate its symptoms and improve quality of life.

• Oral corticosteroids: These are the primary treatment option for Marshall syndrome, often eliciting a prompt response in affected individuals [9].
• Potassium iodide administration: In some cases, potassium iodide has been successful in managing the condition [9].

Other Treatment Considerations

While there is no cure for Marshall-Smith Syndrome, treatment is targeted towards specific symptoms and supportive care is given to ensure comfort and good quality of life [10]. This may involve:

• Intravenous antibiotics: Administered to manage infections and prevent complications [8].
• Antipyretic drugs: Used to control fever and alleviate discomfort [8].

Importance of Multidisciplinary Care

A team approach between families, caregivers, and medical providers is essential for effective management of Marshall syndrome. This ensures that each individual receives tailored care addressing their unique needs and symptoms.

Marshall syndrome, also known as PFAPA (periodic fever, aphthous stomatitis, pharyngitis, cervical adenitis) syndrome, has a differential diagnosis that includes other diseases characterized by periodic fevers and similar symptoms. Some of the conditions that may be considered in the differential diagnosis of Marshall syndrome include:

• Congenital spondyloepiphyseal dysplasia: This is a rare genetic disorder that can cause growth deficiency before birth, spinal malformations, and abnormalities affecting the eyes [1].
• Anetoderma: A condition characterized by smaller lesions that herniate on palpation, which may be considered in the differential diagnosis of Marshall syndrome [9][12].
• Mid-dermal elastolysis: This is a rare skin disorder that can cause mid-dermal elastin degeneration, and may be considered in the differential diagnosis of Marshall syndrome [3][9].
• Stickler syndrome: A genetic disorder that affects the connective tissue, causing hearing loss, eye abnormalities, and short stature. While it shares some similarities with Marshall syndrome, patients with Marshall syndrome more often have short stature and cranial abnormalities [4].
• Familial Mediterranean fever: An inherited condition characterized by recurrent episodes of fever, which may be considered in the differential diagnosis of Marshall syndrome [15].
• Autoimmune Behcet's disease: A rare disorder that causes recurring fevers, skin lesions, and eye inflammation, which may be considered in the differential diagnosis of Marshall syndrome [15].
• Cyclic neutropenia: A rare genetic disorder characterized by periodic episodes of low white blood cell count, which may be considered in the differential diagnosis of Marshall syndrome [15].

It's worth noting that the diagnosis of Marshall syndrome is often made through a process of exclusion, and a high index of suspicion is required to make an accurate diagnosis [2].
