Misdiagnosis and Rare Genetic Syndromes

Understanding misdiagnosis and what we can do to improve rates of confirmed diagnosis for all patients.

A recent study in China of 2040 rare disease patients is shedding light on misdiagnosis in rare disease, and how it may be affected by various factors, including demographics, socioeconomic status, medical history, and access to information about genetic syndromes.

The study overwhelmingly found that rare disease patients who could not access information related to the disease were two to five times more likely to be misdiagnosed. This was true even after accounting for their age, gender, socioeconomic status, and education level. Access to the right information about rare diseases has a considerable influence on whether patients receive a diagnosis rather than a misdiagnosis. 

The study emphasizes the importance of making sure that the information on rare diseases is available through ongoing research and accessible to patients who need it. How this information can be made more accessible is where we should be focusing our efforts in lowering the rate of misdiagnosis amongst rare disease patients.

Promoting genetic counseling as one means of accessing this information is critical, as is building networks of support for families facing a rare disease diagnostic odyssey or diagnosis. 

A misdiagnosis means that a patient and their family cannot access the support and medical care they may need to manage their syndrome or disease. This, in turn, impacts on quality of life. An accurate diagnosis is crucial to ensuring optimum care and care management for patients with a rare genetic syndrome. 

FDNA is committed to utilizing its AI technology and facial recognition software, for genetic analysis, to help rare disease patients and their families find a diagnosis. Reducing the rates of misdiagnosis in the field of genetic and rare diseases is what drives our technology and service.

There may be many obstacles along the way, including: Lack of access to the right medical attention, specialists, and care. Lack of access to the right information about the possible genetic syndrome or rare disease the family faces. The possibility of misdiagnosis. Being stranded in a diagnostic journey, unsure of where and how to access the right information or medical specialists and testing to reach a diagnosis. Lack of support as the family navigates a new reality and future.

Extremely Rare Conditions

All rare diseases and conditions are, as the name suggests, rare. However some are more rare than others. In the US, a rare disease is defined as one that affects less than 200,000 in the entire country. However, each rare disease has its own prevalence rate, and some are extremely rare with just a handful, or sometimes only 1-2, of individuals affected globally.

Diseases That Run in Families

Diseases that run in families are also known as inherited diseases. Some of these have clear genetic causes – and are the result of a specific gene mutation that is inherited in a specific way – others have more complicated causes, including a combination of genetic and environmental reasons.
