Buschke–Ollendorff syndrome (BOS)is a rare genetic disorder associated with LEMD3. It is believed to be inherited in an autosomal dominant manner.[5] It is named for Abraham Buschke and Helene Ollendorff Curth,[6] who described it in a 45-year-old woman. Its frequency is almost 1 case per every 20,000 people, and it is equally found in both males and females.[4]
Signs and symptoms
)
The signs and symptoms of this condition are consistent with the following (possible complications include aortic stenosis and hearing loss[2][4]):
- Osteopoikilosis
- Bone pain
- Connective tissue nevi
- Metaphysis abnormality
Pathogenesis
Buschke–Ollendorff syndrome is caused by one important factor: mutations in the LEMD3 gene (12q14), located on chromosome 12.
Among the important aspects of Buschke–Ollendorff syndrome condition, genetically speaking are:[7][8][9]

- LEMD3 (protein) referred also as MAN1, is an important protein in inner nuclear membrane.
- LEMD3 gene gives instructions for producing protein that controls signaling for transforming growth factor-beta.
- LEMD3 gene helps in the bone morphogenic protein pathway
- Both of the above pathways help grow new bone cells
- BMP and TGF-β pathways controls SMADs proteins, which then bind to DNA
- LEMD3 once mutated, causes a reduction of the protein, which in turn causes excess of the above two pathways.
Diagnosis
)
)
The diagnosis of this condition can be ascertained via several techniques one such method is genetic testing, as well as:[2][3]
- X-ray
- Ultrasound
- Histological test
Differential diagnosis
The differential diagnosis for an individual believed to have Buschke–Ollendorff syndrome is the following:[3]
- Melorheostosis
- Sclerotic bone metastases.
Treatment
In terms of the treatment of Buschke–Ollendorff syndrome, should the complication of aortic stenosis occur then surgery may be required. [4]
Treatment for hearing loss may also require surgical intervention.[4]
