Galloway-Mowat Syndrome: A Rare Neurodegenerative Disorder

Galloway-Mowat syndrome is a rare autosomal recessive neurodegenerative disorder characterized by infantile onset of microcephaly and central nervous system abnormalities. This condition affects various aspects of development, including physical growth, cognitive function, and overall health.

Key Features:

• Infantile onset of microcephaly (small head size)
• Central nervous system abnormalities
• Developmental delay and intellectual disability
• Hypotonia (low muscle tone)
• Hiatus hernia (a type of stomach defect)

Causes and Prevalence: Galloway-Mowat syndrome is a rare genetic disorder, with only a few reported cases in medical literature. The exact cause of the condition is unknown, but it is believed to be inherited in an autosomal recessive pattern.

Galloway-Mowat syndrome is characterized by various developmental and physical abnormalities, including:

• Neurological symptoms: These can include seizures, muscle spasms, and abnormal movements (dystonia) [1].
• Global developmental delay: This refers to a significant delay in the development of cognitive, motor, and language skills [3].
• Progressive microcephaly: Microcephaly is a condition where the head circumference is smaller than average, and it can progress over time [3].
• Hiatal hernia: A hiatal hernia occurs when part of the stomach pushes up through the diaphragm into the chest cavity [4].
• Optic nerve abnormalities: These can include optic atrophy, which refers to the degeneration or shrinkage of the optic nerve [6].
• Movement disorders: These can include extrapyramidal involvement, which refers to problems with movement that are not related to the pyramidal tracts in the brain [8].
• Cerebral and cerebellar atrophy: This refers to the degeneration or shrinkage of the cerebral cortex and cerebellum, which can lead to problems with coordination and balance [8].

It's worth noting that Galloway-Mowat syndrome is a rare condition, and not all individuals will exhibit all of these symptoms. The severity and progression of the symptoms can also vary widely from person to person.

Diagnostic Tests for Galloway-Mowat Syndrome

Galloway-Mowat syndrome (GAMOS) can be diagnosed through various tests and examinations. Here are some of the diagnostic tests used to confirm the condition:

• Genetic testing: Genetic testing is essential for differential diagnosis, as it helps identify the genetic mutations responsible for GAMOS [1]. This test provides full coverage of all coding exons of the WDR73 gene plus 10 bases of flanking noncoding DNA in all available transcripts [6].
• Molecular analysis: Molecular analysis may confirm the diagnosis by identifying specific genetic mutations associated with GAMOS [3].
• Prenatal screening: Prenatal screening and diagnosis are recommended for families with a history of GAMOS, as it can help identify affected fetuses early on [4].

Other Diagnostic Tests

In addition to these tests, other diagnostic procedures may be used to rule out differential diagnoses, such as:

• Fetal ultrafast MRI: Fetal ultrafast MRI has been shown to be a useful tool in determining the extent of central nervous system involvement in fetuses affected with GAMOS [8].
• Physical examination and medical history: A physician will conduct a physical examination and review the patient's medical history to determine if they exhibit symptoms suggestive of GAMOS [10].

Treatment Options for Galloway-Mowat Syndrome

Galloway-Mowat syndrome, a rare neurodegenerative disorder, presents unique challenges in terms of treatment. While there is no specific therapy that has been proven effective, various approaches have been explored to manage the condition.

• Immunosuppressive agents: There is limited evidence on the use of immunosuppressive agents in treating Galloway-Mowat syndrome (5). However, some studies suggest that these medications may be beneficial in certain cases.
• Captopril and indomethacin regimen: A treatment protocol involving captopril and indomethacin was used in five children from 1997 to 1998 (4). The effectiveness of this approach is unclear.
• Medical therapy: Medical therapy is the mainstay of treatment for Galloway-Mowat syndrome, with a focus on managing symptoms such as seizures and kidney issues (8).
• Dialysis and medications: Kidney problems can be treated with dialysis or medications, while symptoms like seizures may also require medical attention (9).

It's essential to note that the effectiveness of these treatment options is not well established due to the rarity of Galloway-Mowat syndrome. A multidisciplinary approach involving specialists from various fields may be necessary to provide comprehensive care.

Differential Diagnosis of Galloway-Mowat Syndrome

Galloway-Mowat syndrome (GAMOS) is a rare genetic disease characterized by early-onset nephrotic syndrome and microcephaly with brain anomalies. When considering the differential diagnosis for GAMOS, several conditions should be taken into account.

• Nephrotic Syndrome: Early-onset steroid-resistant nephrotic syndrome (SRNS) is a key feature of GAMOS. Other conditions that can present with SRNS include:
  • Congenital nephrotic syndrome: A rare condition characterized by severe proteinuria and edema in the first few months of life [1].
  • Focal segmental glomerulosclerosis (FSGS): A common cause of nephrotic syndrome in children, which can be associated with genetic mutations [2].
• Microcephaly: Microcephaly is a hallmark feature of GAMOS. Other conditions that can present with microcephaly include:
  • Primary microcephaly: A rare condition characterized by small head size and intellectual disability [3].
  • Microcephalic primordial dwarfism: A severe form of microcephaly associated with growth retardation and developmental delay [4].

Key Features to Consider

When differentiating GAMOS from other conditions, the following key features should be considered:

• Early-onset nephrotic syndrome: GAMOS typically presents with early-onset SRNS.
• Microcephaly: Microcephaly is a hallmark feature of GAMOS.
• Brain anomalies: GAMOS can present with various brain anomalies, including gyral abnormalities and seizures.
