Etiopathogenesis

mutation in the p63 gene mapped on chromosome 3q27. The transcription co-activator p63 is crucial for the correct development of the extremities and ectodermal adnexa (nails, hair, glands). Gene mutations lead to corresponding malformation syndromes.

Clinical features
This section has been translated automatically.

There may be significant differences in the appearance and severity of the syndrome (slight to full-blown with all possible disorders).
  • Cleft palate or cleft lip and palate.
  • Mostly cleft hand and foot.
  • Eye: Atresia of the lacrimal-nasal ducts, photophobia, chronic blepharitis and conjunctivitis, dacryocystitis, blepharophimosis.
  • Mouth: partial anodontics or microdontics.
  • Hair: Blond, sparse, curly; hypoplasia of eyebrows and eyelashes.
  • Nail dysplasia, hypoplasia of nipples, lentigines.

Note(s)

Mutations in the p63 gene are found in several syndromes, including non-syndromal hand and foot clefts, EEC syndrome (ectrodactyly-ectodermal-dysplasia-cleft-lip/palate syndrome), LMS syndrome (limb-mammary syndrome), Hay-Wells syndrome.
