Clinical featuresThis section has been translated automatically.
- There may be considerable differences in the appearance and severity of the syndrome (slight variations to full-blown with all possible disorders).
- Cleft palate or cleft lip and palate. Mostly cleft hand and foot. Nail dysplasia, hypoplasia of the nipples, hearing loss.
- Eye: Atresia of the lacrimal ducts, photophobia, chronic blepharitis and conjunctivitis, dacryocystitis, blepharophimosis, blue iris (pigment deficiency).
- Mouth: partial anodontics or microdontics, especially the septum-like development of the incisors
- Nails: Nail syplasia
- Hair: blond, sparse, curly; hypoplasia of eyebrows and eyelashes, atrophy
- In later life folliculitis-decalvans-like inflammation of the scalp with consecutive scarred alopecia(pseudopelade).

Case report(s)This section has been translated automatically.
Two boys and their mother were affected.
Patient 1 (12 years) had a mild bilateral syndactyly between the 3rd and 4th finger, a cleft palate which had been surgically repaired, hypodontia and enamel anomalies with pronounced caries. The hair was sparse, light and thin, the nails were thin and had transverse grooves. The skin was dry and there was a mild hypohidrosis. Due to a lacrimal duct atresia, keratoconjunctivitis occurred repeatedly. In addition there were anomalies of the genitourinary tract with hypospadias and left-sided cryptorchidism. In addition there was conductive hearing loss and a slight auricular dysplasia.
Patient 2 was his 10-year-old brother with also light hair, dental anomalies, unilateral cleft palate and a lacrimal canal atresia. The patient also had an increasing conductive hearing loss.
The 40-year-old mother suffered from a left-footed ectodactyly and an almost complete cutaneous syndactyly between the 4th and 5th finger of the right hand. The hair was also quite light, showing sparse growth. The nails were hypoplastic. Furthermore, a partial anodontia was visible, but without cleft formation. There were recurrent eye infections, because the patient also had a bilateral lacrimal duct closure, which made a corneal transplantation necessary at the age of 28 years.
All patients showed normal mental development.
