Monogenic Mendelian disorders in general neurological practice

Area of Science:

• Neurology
• Genetics
• Clinical Medicine

Background:

• Monogenic Mendelian disorders are inherited conditions caused by mutations in a single gene.
• These disorders can present with a wide range of neurological symptoms.
• General neurology clinics encounter a diverse patient population, but the frequency of specific rare disorders may be low.

Purpose of the Study:

• To determine the frequency and types of monogenic Mendelian disorders seen in general neurology outpatient clinics.
• To assess the implications of these findings for medical education and neurological training.
• To provide recommendations for the optimal management of patients with monogenic disorders.

Main Methods:

• Observational study design.
• Retrospective analysis of patient data over a 6-year period.
• Identification and classification of monogenic Mendelian disorders based on diagnosis.

Main Results:

• Fifty-three patients with 16 distinct monogenic Mendelian disorders were identified.
• Huntington's disease and neurofibromatosis type 1 were the most frequently diagnosed disorders.
• The overall frequency of these disorders in general neurology clinics was found to be low.

Conclusions:

• The low prevalence of monogenic Mendelian disorders in general neurology settings highlights the need for specialized expertise.
• Continuing medical education and neurological training should emphasize the recognition and management of these rare conditions.
• Referral to specialist clinics is advised for comprehensive diagnosis, genetic counseling, testing, and management.
