Welcome ! to the MHE Research Foundation website The MHE Research Foundation is a nonprofit 501(c)(3) organization dedicated to the support of, Researchers, Physicians and Families, Dealing with (MHE) Multiple Hereditary Exostoses Syndrome/(MO) Multiple Osteochondroma Syndrome a Rare Genetic Bone Disease. The MHE Research Foundations five point mission is to REACH, advance & support the following. |
| |||||||||||||||||||
| RESEARCH, to assist and support researchers in order to one day discover a treatment/cure for MHE/MO/HME. Our foundation works hand in hand with researchers from around the world in this mission. EDUCATION, to provide vital clinical informational guides benefiting both families and physicians. ADVOCACY, bring awareness about this rare neglected bone disease throughout the world. CLINICAL, to help provide resources to families enabling them to locate the medical care they require. HOPE, the research being conducted on MHE/MO/HME & the informational resources will bring a better quality of life to the families affected by this syndrome around the world.

| JUNE 9, 2012 Journal "The Scientist" Bones to Brains - Autism- Relevant Behavioral Phenotype Click here to read this article MARCH 12, 2012 PRESS RELEASE RESEARCH & THE SANFORD BURNHAM |
MHE / MO / HME is a genetic bone disorder in which benign cartilage-capped bone tumors grow outward from the metaphyses of
long bones, growth plates or from the surface of flat bones throughout the body. The severity of this disease varies widely.
Some patients may have as few as two tumors, but most patients develop many more and the numbers of tumors can run into
the hundreds.
These cartilage-capped bone tumors are called Exostoses / Osteochondroma and may be sessile or pedunculated and vary
widely in size and shape. Pedunculated Exostoses / Osteochondroma is when a stalk is present, the structure is called
pedunculated. These have a Broccoli like appearance with stalk and growth towards the end of the stalk. Sessile Exostoses /
Osteochondroma have a broad-base attachment to the outer bone, called the "cortex". These have a lumpy / bumpy appearance
(When no stalk is present, these are called sessile).
These Exostoses / Osteochondromas can cause numerous problems, including: compression of peripheral nerves or blood
vessels; irritation of tendons and muscles resulting in pain and loss of motion; skeletal deformity; short stature; limb length
discrepancy; chronic pain and fatigue; mobility issues; early onset arthritis; and an increased risk of developing malignant tumor
transformation (chondro-sarcoma) reported risk of 2%-5% over life time. It is not uncommon for MHE / MO / HME patients to
undergo numerous surgical procedures throughout their lives to remove painful or deforming Exostoses / Osteochondromas,
following these surgeries abnormal scarring can accrue with keloid formation. MHE / MO / HME patient also need to undergo
surgeries to correct the bone deformities as well as limb length discrepancies and improve range of motion. New scientific
findings are also showing autism relevant behavioral phenotype connected to MHE / MO / HME.
Surgery, physical therapy and pain management are currently the only options available to MHE / MO / HME patients, but their
success varies from patient to patient and many struggle with chronic pain, fatigue and mobility problems throughout their lives.
MHE / MO / HME is a genetic autosomal dominant hereditary disorder. This means that a patient with MHE / MO / MHE has a 50%
chance of transmitting this disorder to his / her children. Approximately 10% -20% of individuals with MHE / MO / HME have the
condition as a result of a spontaneous mutation are thus the first person in their family to be affected.
There are two known genes found to cause MHE / MO / HME they are EXT1 located on chromosome 8q23-q24 and EXT2 located
on chromosome 11p11-p12. Approximately 60 to 70 % of mutations are located in the EXT1 gene and 20 to 30% are located in
the EXT2 gene. In 10 to 20% of the patients, no mutation is found.
