DefinitionThis section has been translated automatically.
Malformation syndrome with thinning hair growth, phalangeal cone epiphyses and typical facial dysmorphia with hand dysplasia, diffuse hypotrichia with easily breaking off hair and Hertogeschem signs. In type II there are also multiple cartilaginous exostoses.

EtiopathogenesisThis section has been translated automatically.
- Type I: Autosomal dominant inheritance with variable penetrance of deletion mutations of the TPRS1 gene mapped on gene locus 8q24.1.
- Type II: Mostly spontaneous, less frequently autosomal-dominant inherited deletions of the TPRS1 gene as well as of the EXT1 gene mapped on gene locus 8q24.11-q24.13.
Clinical featuresThis section has been translated automatically.
cone epiphyses on the phalanges. Pear-shaped deformation of the nose (soft nasal cartilage), moderately conspicuous in frontal view. High philtrum, thin, thinning hair, possibly early alopecia. Often Perthes-like, unilateral or bilateral changes of the femoral head. Mental retardation (especially with type II).
