Summary about Disease
Borjeson-Forssman-Lehmann syndrome (BFLS) is a rare, X-linked recessive genetic disorder primarily affecting males. It is characterized by intellectual disability, distinctive facial features, hypogonadism, obesity, and epilepsy. Females who carry the gene mutation may show milder symptoms.
Symptoms
Intellectual disability (moderate to severe)
Distinctive facial features (large ears, prominent supraorbital ridges, ptosis, deep-set eyes)
Hypogonadism (small testes, delayed puberty)
Obesity (especially truncal obesity)
Epilepsy
Gynecomastia (enlargement of male breast tissue)
Short stature
Tapered fingers and broad toes
Visual impairment
Hearing impairment
Causes
BFLS is caused by mutations in the PHF6 gene located on the X chromosome. This gene is involved in the regulation of cell growth and development. Because it is X-linked recessive, males are more severely affected as they only have one X chromosome. Females are usually carriers, but some may show milder symptoms if they have skewed X-inactivation.
Medicine Used
There is no specific cure for BFLS. Treatment focuses on managing the individual symptoms:
Antiepileptic drugs for seizures
Hormone replacement therapy for hypogonadism
Behavioral therapy and educational support for intellectual disability
Weight management strategies for obesity
Medications to help in the treatment of behavior changes.
Surgery for gynecomastia in severe cases.
Is Communicable
No, Borjeson-Forssman-Lehmann syndrome is not communicable. It is a genetic disorder caused by a gene mutation and cannot be spread from person to person.
Precautions
There are no specific precautions to prevent BFLS as it is a genetic disorder. Genetic counseling is recommended for families with a history of the syndrome to assess the risk of recurrence in future pregnancies.
How long does an outbreak last?
BFLS is not an outbreak, but a genetic condition. There is no specific outbreak period since it is a lifelong condition.
How is it diagnosed?
Diagnosis of BFLS typically involves:
Clinical evaluation of the characteristic symptoms and physical features
Genetic testing to identify mutations in the PHF6 gene
Neurological examination, including EEG to assess for epilepsy
Hormonal testing to evaluate for hypogonadism
Developmental assessment to evaluate intellectual disability
Timeline of Symptoms
The timeline of symptom onset can vary:
Infancy/Early Childhood: Developmental delays, distinctive facial features may become apparent.
Childhood: Intellectual disability, seizures, obesity may become more evident.
Adolescence: Delayed puberty, hypogonadism, gynecomastia may become apparent.
Important Considerations
Early diagnosis and intervention are crucial to optimize developmental outcomes.
Multidisciplinary care involving specialists in genetics, neurology, endocrinology, and developmental pediatrics is essential.
Affected individuals and their families may benefit from support groups and resources for individuals with intellectual disabilities.
Genetic counseling is important for family planning.
