Hypertrichosis, Fallot tetralogy, growth and developmental delay

Area of Science:

• Genetics
• Pediatrics
• Dermatology

Background:

• Syndromal hypertrichoses are rare genetic disorders characterized by excessive hair growth.
• Distinguishing between different types of syndromal hypertrichoses is crucial for accurate diagnosis and management.

Observation:

• A female patient presented with prenatal and postnatal growth deficiency.
• She exhibited tetralogy of Fallot, generalized hypertrichosis lanuginosa, and trichomegaly (very long eyelashes).
• Additional features included brain atrophy with epilepsy, and puffy hands and feet.

Findings:

• The patient's unique combination of symptoms suggests a novel syndromal hypertrichosis.
• This condition appears pathogenetically related to, yet clinically distinct from, Ambras syndrome and Oliver-McFarlane syndrome.
• The findings expand the spectrum of known genetic disorders associated with hypertrichosis.

Implications:

• This case highlights the importance of recognizing rare genetic syndromes.
• Further research is needed to elucidate the specific genetic basis and pathogenesis of this new entity.
• Understanding this distinct syndrome can improve diagnostic accuracy and inform future therapeutic strategies.
