Descriptor picnodisostosis
Scope note: Síndrome autosómico recesivo poco frecuente caracterizado por cierre retrasado de las SUTURAS CRANEALES, baja estatura, ACROSTEOLISIS de las falanges distales, ANOMALÍAS MAXILOFACIALES e incremento de la densidad ósea que da lugar a frecuentes FRACTURAS ÓSEAS. Se asocia a defectos de la RESORCIÓN ÓSEA debidos a mutaciones de la cisteína proteasa lisosómica CATEPSINA K.

Scope note: Rare autosomal recessive syndrome characterized by delayed closing of CRANIAL SUTURES, short stature, ACRO-OSTEOLYSIS of distal phalanges, dental and MAXILLOFACIAL ABNORMALITIES and an increase in bone density that results in frequent BONE FRACTURES. It is associated with BONE RESORPTION defect due to mutations in the lysosomal cysteine protease CATHEPSIN K.
