The study was begun after a litter of seven puppies was whelped; five of which showed some form of dwarfism. A search has begun to locate other dogs medically diagnosed with dwarfism. Pedigree analysis of the known affected dogs shows some common ancestry among them. However, most of the general population of Chesapeakes also shares common ancestry with these affected dogs; therefore pedigree analysis alone is not sufficient to eliminate the gene from the population. It is hoped that a genetic marker or mutation test can be developed to detect carriers. This study is privately funded, so no ACC funds are needed; however, the researchers are looking for affected dogs in order to help with development of a gene test. Anyone with an affected dog can contact Dr. Switzer, who is coordinating the effort to obtain dogs for this research. A blood sample and copy of pedigree from affected dogs are what is needed right now.
HHMI News: Physician Postdoctoral Fellow Pursues Cause Of Dwarfism
Michael Naski has helped to identify a genetic mutation that can causebones to stop growing, leading to a form of dwarfism. RESEARCH NEWS.
http://www.hhmi.org/news/naski.html

Extractions: Michael Naski, an HHMI physician postdoctoral fellow at Washington University School of Medicine in St. Louis, is zeroing in on the genes that cause dwarfism. Suddenly, Naski had his work cut out for him. "The question burning in the field was, Just how do these mutations affect receptor function?" said Naski, an HHMI physician postdoctoral fellow at Washington University School of Medicine in St. Louis. "It was an easy question to dive into." Now, Naski has begun to find answers. In the June, 1996, issue of Nature Genetics , he and colleagues reported that several mutations can jumpstart a protein receptor that inhibits bone growth. The receptor is called fibroblast growth receptor (FGF) 3. When mutated, FGF receptor 3 can cause bones to simply stop growing. Depending on the mutation, an individual with a faulty FGF receptor 3 gene may die shortly after birth or endure a range of problemsfrom abnormal curvature of the spine to arthritisthat accompany dwarfism. Normally, longitudinal bonessuch as those in our arms and legsgrow with the guidance of cartilage cells. Found at the end of bones, these cells weave a cartilage-based matrix into which bones extend. Like a paint-by-numbers set, cartilage cells shape an outline that bone fills in. The FGF receptor 3 sits quietly on cartilage cells until activated by a protein called fibroblast growth factor (FGF). When signalled, the receptor stops the matrix-forming cartilage cells in their tracks. Researchers are uncertain just how this process works.

http://www.smallhorse.com/ExpertArticles/dwarf.html

Extractions: I'd like to add that the folks who've contributed to this site are being extremely generous and honest in sharing these little guys. In order to lessen the chances of producing dwarves, or eradicate the risk altogether, we need to learn all we can about them as well as find a way to test for the gene that causes it. Since it is such a prevalent problem in our breed, we feel that sharing what we learn and know is the first major step in this process which can only be good for the breed as a whole. These exceptional individuals are by no means a goal of breeding, but neither should they be kept secret. We don't know yet for sure the causes of dwarfism. Join me in applauding the contributors' bravery and farsightedness. If you have anything to contribute to this page, please email me

I Won't Grow Up: The Causes Of Psychogenic Dwarfism

Extractions: This paper was written by a student in a course at Bryn Mawr College, and reflects that student's research and thoughts at the time the paper was written. Like other things on Serendip , the paper is not intended to be "authoritative" but is instead provided to encourage others to themselves learn about and think through subjects of interest, and, by providing relevant web links, to serve as a "window" to help them do so. Web links were active as of the time the paper was posted but are not updated. Biology 202 On Serendip "All children, except one, grow up. They soon know that they will grow up, and the way Wendy knew was this. One day when she was two years old she was playing in a garden, and she plucked another flower and ran with it to her mother. I suppose she must have looked rather delightful, for Mrs. Darling put her hand to her heart and cried, "Oh, why can't you remain like this for ever!" This was all that passed between them on the subject, but henceforth Wendy knew that she must grow up. You always know after you are two. Two is the beginning of the end."-J.M. Barrie, Peter Pan Psychogenic dwarfism is a growth disorder that is observed between the ages of 2 and 15, caused by extreme emotional deprivation. The symptoms include decreased growth hormone (GH) secretion, very short stature, weight that is inappropriate for the height, and immature skeletal age. This disease is a progressive one, and as long as the child is left in the stressing environment, his or her cognitive and linear abilities continue to degenerate
Gene Discovered For Form Of Dwarfism
Release Date June 30, 1995. Quick Links. News Releases Index Searchthe Archives. Legal Disclaimer. Gene Discovered For Form of dwarfism.
http://www.uthouston.edu/forMedia/newsreleases/nr2001/genetics/dwarf.html

Extractions: The discovery is reported in the July 1 issue of the journal Nature Genetics. The abnormal gene is located on chromosome 19 and is called the cartilage oligomeric matrix protein (COMP) gene for its role in making this particular form of protein, which acts as a building block in the body. The COMP gene is normally present in all individuals, and mutations in this gene cause pseudoachondroplasia. "With the identification of the pseudoachondroplasia gene we plan to study the normal interactions of this protein in order to understand how the abnormal protein disrupts normal bone growth and development," said Hecht, associate professor in the UT-Houston Medical School division of medical genetics. Pseudoachondroplasia is a condition marked by disproportionate short stature. Bowing or knock-knee deformities of the legs are common in childhood and often require surgical correction. In adulthood, all pseudoachondroplastic dwarves suffer from osteoarthritis and approximately 50 percent require hip replacement.
