Fraser Syndrome

1. Disease Summary:

Fraser syndrome, also known as cryptophthalmos-syndactyly syndrome, is a rare autosomal recessive genetic disorder characterized by a spectrum of congenital anomalies. Key features include cryptophthalmos (failure of eyelids to separate), syndactyly (fusion of fingers and/or toes), and various abnormalities of the genitalia and urinary tract. Other associated anomalies may include malformations of the nose, ears, larynx, and renal system, as well as developmental delays. The syndrome is caused by mutations in three genes: FRAS1, FREM2, and GRIP1, which disrupt normal embryonic development (GARD, 2023).

2. Global Prevalence and Disease Burden:

Fraser syndrome is extremely rare, with an estimated prevalence of approximately 1 in 200,000 live births, and it occurs in about 1 in 10,000 stillbirths (GARD, 2023). The economic burden of Fraser syndrome is difficult to quantify due to its rarity; however, the costs associated with managing congenital anomalies, surgical interventions, and long-term care can be significant. Families may face high medical expenses, loss of income due to caregiving responsibilities, and psychological impacts from the challenges of raising a child with complex medical needs.

3. Unmet Medical Need:

Despite the known features of Fraser syndrome, several unmet medical needs persist:

Awareness and Diagnosis: There is a significant lack of awareness among healthcare professionals regarding Fraser syndrome, which can lead to delays in diagnosis. Many cases are not recognized until later in life, which can hinder timely intervention (PMID: 6704688).
Comprehensive Care: Patients often require multidisciplinary care involving geneticists, pediatricians, surgeons, and other specialists. However, there is a lack of coordinated care pathways, leading to fragmented services and inadequate management of associated health issues (NORD, 2023).
Psychosocial Support: Families affected by Fraser syndrome often experience emotional and psychological stress due to the complexities of the condition. There is a need for better psychosocial support services to help families cope with the challenges they face (Rare Diseases: Needs and Impact for Patients and Families, 2023).
Research and Treatment Development: There is limited research focused on Fraser syndrome, resulting in a lack of targeted therapies. Current treatment options primarily address symptoms rather than the underlying genetic causes, highlighting the need for more research into potential therapies (NORD, 2023).

4. Current Treatment Options:

Currently, treatment for Fraser syndrome is symptomatic and supportive, focusing on managing the various congenital anomalies associated with the condition:

Surgical Interventions: Patients may require multiple surgeries to correct physical anomalies, such as oculoplastic surgery for cryptophthalmos, orthopedic surgery for syndactyly, and urological surgery for genital and urinary tract abnormalities (Orphanet, 2023).
Rehabilitative Services: Physical therapy and occupational therapy may be necessary to address developmental delays and improve functional outcomes (NORD, 2023).
Genetic Counseling: Families are often advised to seek genetic counseling to understand the implications of the disorder and the risks for future pregnancies (GARD, 2023).

Despite these options, the effectiveness of treatments can vary widely, and many patients may not achieve optimal outcomes due to the complexity of their conditions.

5. Current Clinical Trials:

As of now, there are limited clinical trials specifically targeting Fraser syndrome. Most research focuses on understanding the genetic basis of the disorder and exploring potential therapeutic avenues. Ongoing studies may include genetic research and the development of gene therapies, but specific trials are not widely reported in clinical trial registries.

6. Additional Context:

Fraser syndrome is part of a broader category of rare diseases that often face challenges in research funding, awareness, and treatment development. Advocacy groups play a crucial role in raising awareness and supporting affected families. Increased collaboration among researchers, healthcare providers, and patient advocacy organizations is essential to address the unmet needs of individuals with Fraser syndrome and improve their quality of life.
