Treacher Collins–Franceschetti Syndrome (TCFS)

Treacher Collins–Franceschetti Syndrome (TCFS) is a genetic disorder affecting the facial bones and tissues. People with TCFS may have a distinctive appearance due to changes in the structure of the face.

Types:

There aren’t distinct “types” of TCFS, but the severity and appearance can vary between individuals. Some have milder symptoms, while others may have more noticeable facial differences.

Causes:

Actually, the primary cause of TCFS is genetic mutations. But for simplification, let’s break down its genetic basis:

  1. Mutation in TCOF1 gene: Most common cause.
  2. Mutation in POLR1D gene.
  3. Mutation in POLR1C gene. Though primarily caused by these gene mutations, the exact manifestation may be influenced by other, not entirely understood, genetic and environmental factors.
  4. Gene Mutations: Most cases of TCS are due to changes in the TCOF1, POLR1C, or POLR1D genes. While the above genes are the primary causes, various mutations within these genes can lead to the syndrome. But, simply put, it’s like having a typo in the instruction manual that the body uses for face development.

Symptoms:

TCS leads to various facial abnormalities. Here are the most common:

  1. Droopy Eyelids: The eyelids may droop down.
  2. Small Jaw: The lower jaw might be noticeably smaller.
  3. Small or Absent Ears: The ears might be very small or even missing.
  4. Hearing Loss: Due to abnormalities in the ear.
  5. Downward Slanting Eyes: The opening of the eyes might slant downwards.
  6. Cleft Palate: A gap in the roof of the mouth.
  7. Hair growing from Cheek: Hair might grow from the cheek to the sideburns.
  8. Vision Problems: Issues related to abnormal eye development.
  9. Airway Obstruction: Breathing problems due to the small jaw.
  10. Feeding Difficulties: Problems with eating due to the jaw and palate.
  11. Speech Difficulties: Talking might be harder because of the palate.
  12. Dental Problems: Issues like tooth alignment because of the small jaw.
  13. Flat Cheekbones: The bones of the cheeks might be flat.
  14. Narrow Face: The face might appear more narrow than usual.
  15. Nose Deformities: The nose might look different.
  16. Scalp Defects: Issues on the top part of the head.
  17. Eye Vision Issues: Like nearsightedness or farsightedness.
  18. Chronic Ear Infections: Due to ear abnormalities.
  19. Difficulty Swallowing: Problems with swallowing because of the throat structure.
  20. Facial Asymmetry: One side of the face might look different from the other.

Diagnostic Tests: TCS can be diagnosed with:

  1. Physical Exam: A doctor looks for facial abnormalities.
  2. Hearing Test: To check for hearing loss.
  3. CT Scan: Detailed images of the head and face.
  4. MRI: Another imaging test for the face and skull.
  5. X-rays: To see bone structures.
  6. Genetic Testing: To find gene mutations.
  7. Ultrasound: For pregnant women, to see the baby’s face.
  8. Genetic testing: To find the specific mutation.
  9. CT scan: To see facial bone structure.
  10. MRI: For detailed images of the face.
  11. Ear examination: To check ear abnormalities.
  12. Dental X-rays: To examine teeth alignment.
  13. Airway evaluation: To assess breathing difficulties.
  14. Eye examination: To check for vision problems.
  15. Speech assessment: To understand any speech challenges.
  16. Swallow study: For feeding issues.
  17. Bone X-rays: To see bone abnormalities.
  18. Ultrasound: During pregnancy to detect abnormalities.
  19. Amniocentesis: Test during pregnancy.
  20. Chromosome analysis: To rule out other conditions.
  21. Prenatal cell-free DNA screening: Check fetus DNA in the mother’s blood.
  22. Blood tests: To rule out other conditions.
  23. Genetic counseling: For family planning.
  24. Skin biopsy: Rarely used.
  25. Endoscopy: To see the throat and airways.

Treatments:

TCFS treatments aim to improve appearance and function.

  1. Reconstructive surgery: For bone structure.
  2. Hearing aids: To improve hearing.
  3. Speech therapy: For speech challenges.
  4. Dental care: To manage dental issues.
  5. Airway management: For breathing problems.
  6. Feeding therapy: To assist with eating.
  7. Eyelid surgery: To correct drooping.
  8. Ear surgery: To fix or reconstruct ears.
  9. Bone grafting: To rebuild cheekbones.
  10. Cleft palate repair.
  11. Tracheostomy: To help with breathing.
  12. Orthodontic treatment: For teeth alignment.
  13. Physical therapy: For muscle strength.
  14. Audiology care: For ear health.
  15. Nasal surgery: For better breathing.
  16. Counseling: Emotional and psychological support.
  17. Support groups: To connect with others.
  18. Nutritional counseling: For dietary needs.
  19. Vision therapy: To manage eye problems.
  20. Prosthetics: Like artificial ears.
  21. Jaw surgery: To fix a small jaw.
  22. Nasal stents: Open nasal passages.
  23. Laser surgery: For skin abnormalities.
  24. Cosmetic tattooing: For missing eyelashes.
  25. Special education: For learning challenges.
  26. Communication devices: For non-verbal individuals.
  27. Bone conduction hearing devices.
  28. Craniofacial team care: Holistic treatment approach.
  29. Sleep studies: For sleep-related problems.
  30. Breathing devices: Like CPAP for sleep apnea.

Drugs:

While there isn’t a specific drug for TCFS, medications may be prescribed for associated conditions:

  1. Pain relievers: Post-surgery.
  2. Antibiotics: For infections.
  3. Nasal sprays: For nasal congestion.
  4. Ear drops: For ear infections.
  5. Eye drops: For dry or irritated eyes.

  9. Anti-anxiety medications.
  10. Hearing aid batteries.
  11. Topical creams: For skin care.
  12. Vitamins: For overall health.
  13. Dietary supplements: For nutritional needs.
  14. Oral devices: For dental issues.
