Achondroplasia Achondroplasia Achondroplasia, also known as "short limb dwarfism" or "chondrodystrophia fetalis," is a disease in which there is a disorder in bone growth. It is one of the oldest birth defects and it happens for many different reasons. For some, it is inherited from the family or from their ethnic background and for others, it could just be genetic medical conditions. Many times, this disease is caused by an abnormal gene passed from one parent to the child. In most cases the parents are average size, but the gene is a new mutation. Most of the time the parents have no other children with achondroplasia and there is a very small chance of having another child with this condition. Some of the causes for achondroplasia are known and can be treated, but for most cases there is still research needed to be done. A couple of groups working on research for this disease are the Human Growth Foundation, the Little People of America and the Short-Stature Foundation. Achondroplasia affects about one child in every twenty-five thousand to forty thousand births. A person who is affected by it will have a normal torso and short arms and legs. achondroplasia, dwarfism, dwarf, disease, chondrodystrophia, fetalis, upper, short, child, author, one, lower, gene, children, cases, very, thousand, research, parents, normal, legs, larger, known, jan, growth, genetic, flat, family, births, birth, because, average, available, arms, about, working, wide, weakened, way, walk, vol1a-akbayes, unexpected, twenty-five, treated, torso, times, time, thighs, tend, teeth, stubby, straight, spine, spinal
