Occurrence/EpidemiologyThis section has been translated automatically.
Incidences range from 1:50,000 to 1:250,000 live births.
EtiopathogenesisThis section has been translated automatically.
Ätiopathogenetisch the OFD type I is counted to the ciliopathies. Cilia are thin, tubular extensions of the cell surface. They are used for locomotion and are involved in various cell biological signalling pathways. X-linked dominant or X-linked recessive inheritance of mutations (99 mutations are known) of the OFD-1 gene, which is mapped on the gene locus Xp22.2-p22.3 and leads to the expression of a non-functional OFD-1 protein. XY combinations are usually lethal. The OFD-1 gene seems to play an important role in the morphogenesis of certain body parts. The OFD-1 protein is ubiquitously expressed during embryonic development and postpartum. It is located at the base of the cilia and plays an important role in their development.
Clinical featuresThis section has been translated automatically.
- Integument: Multiple milia appear in the facial region. These are rfeversible in the course of life.
- Further possible are brittle, thinning hair (hypotrichosis) and circumscribed alopecia. The hair growth disturbances remain openly absent for the whole life.
- Extracutaneous manifestations are: combination of facial and acral malformations with hyperplastic multiple frenula of the oral cavity, delayed tooth growth up to tooth aplasia, lobes and notches of the tongue, tongue fibromas and median cleft lip and palate. Hypoplasia of the nasal tip cartilage. Polydactyly, syndactyly and brachydactyly can also be pronounced.
DiagnosisThis section has been translated automatically.
Main symptoms:
- only female patients (OFD-1 type leads to death already intrauterine in male fetuses)
- Hypotrichosis
- Milia (facial skin)
- Brachydactyly
- Dysmorphia of the face (hypertelorism, asymmetry, widened nasal root)
- Mutation of the OFD-1 gene
Secondary symptoms:
- Tongue fibroids
- Frenula (hyperplastic, multiple)
- Dental aplasia
- Abnormalities of the CNS
