Encyclopedia Index A Home Encyclopedia Encyclopedia Index A Achondroplasia Definition Achondroplasia is the most common cause of dwarfism, or significantly abnormal short stature. Description Achondroplasia is one of a number of chondodystrophies, in which the development of cartilage, and therefore, bone is disturbed. The disorder appears in approximately one in every 10,000 births. Achondroplasia is usually diagnosed at birth, owing to the characteristic appearance of the newborn. Normal bone growth depends on the production of cartilage (a fibrous connective tissue). Over time, calcium is deposited within the cartilage, causing it to harden and become bone. In achondroplasia, abnormalities of this process prevent the bones (especially those in the limbs) from growing as long as they normally should, at the same time allowing the bones to become abnormally thickened. The bones in the trunk of the body and the skull are mostly not affected, although the opening from the skull through which the spinal cord passes (foramen magnum) is often narrower than normal, and the opening (spinal canal) through which the spinal cord runs in the back bones (vertebrae) becomes increasingly and abnormally small down the length of the spine. Causes and symptoms Achondroplasia is caused by a genetic defect. It is a dominant trait, meaning that anybody with the genetic defect will display all the symptoms of the disorder. A parent with the disorder has a 50% chance of passing it on to the offspring. Although achondroplasia can be passed on to subsequent offspring, the majority of cases occur due to a new mutation (change) in a gene. Interestingly enough, the defect seen in achondroplasia is one of only a few defects known to increase in frequency with increasing age of the father (many genetic defects are linked to increased age of the mother).

Achondroplasia is a genetic (inherited) bone disorder that occurs in one in 20,000 live births. Achondroplasia is the most common type of dwarfism, in which the child's arms and legs are short in proportion to body length. Further, the head is often large and the trunk is normal size. The average height of adult males with achondroplasia is 52 inches (or 4 feet, 4 inches). The average height of adult females with achondroplasia is 49 inches (or 4 feet, 1 inch). What causes achondroplasia? Achondroplasia is inherited by an autosomal dominant gene that causes abnormal cartilage formation. Autosomal dominant inheritance means that the gene is located on one of the autosomes (chromosome pairs 1 through 22). This means that males and females are equally affected. Dominant means that only one gene is necessary to have the trait. When a parent has a dominant trait, there is a 50 percent chance that any child they have will also inherit the trait. So, in some cases, the child inherits the achondroplasia from a parent with achondroplasia. The majority of achondroplasia cases (80 percent), however, are the result of a new mutation in the family - the parents are of average height and do not have the abnormal gene. As mentioned, persons with achondroplasia have a 50 percent chance to pass the gene to a child, resulting in the condition. If both parents have achondroplasia, with each pregnancy, there is a 50 percent chance to have a child with achondroplasia, a 25 percent chance that the child will not inherit the gene and be of average height, and a 25 percent chance that the child will inherit one abnormal gene from each parent, which can lead to severe skeletal problems that often result in early death.

DNA Analysis ACHONDROPLASIA B A C K G R O U N D Achondroplasia is the most common genetic form of non-lethal dwarfism, affecting approximately 1 in 15,000 individuals. Although the disorder is dominant, 80-90% of cases occur in families where neither one of the parents is affected. Achondroplasia is caused by certain mutations in the gene that codes for the fibroblast growth factor receptor 3 (FGFR3). Greater than 99% of individuals with achondroplasia have an alteration in one of their two FGFR3 genes at nucleotide 1138, consisting of either a G-to-A transition or a G-to-C transversion. Both mutations cause the 380 th amino acid to be changed from glycine to arginine (G380R). A mutation in only one FGFR3 gene is sufficient to cause the disease. Our DNA panel tests for both of these mutations.

printer friendly ACHONDROPLASIA home more about us in your area conditions information ... how you can help search this site Achondroplasia is a rare, genetic condition, but one of the most common types of restricted growth with disproportionate short stature. Achondroplasia is mainly a physical condition with affected people having normal intelligence. Many practical difficulties can be overcome with a little imagination and there is no reason why someone with achondroplasia should not participate in most activities. It is important that the person themselves is able to find their own limits and boundaries and that these are not imposed by society. Achondroplasia literally means "no cartilage growth," but in reality it refers to poor bone growth resulting in shortened limbs. The tissues around the limbs are not affected and continue to grow leading to bulky arms and legs. Growth charts designed specifically for children with achondroplasia should be used to monitor growth. People with achondroplasia have a range of characteristics including: A near normal trunk length with shorter arms and legs A large head with prominent forehead and flattened bridge of the nose An increased curvature of the lower spine (lumbar lordosis) Bowing of the lower legs Possible crowded teeth Short, broad feet and hands with separation between middle and ring fingers (the "trident" hand)

Information Brief on: Developmental Disabilities ACHONDROPLASIA Achondroplasia is a musculoskeletal defect that occurs in about 1/26,000 infants. Achondroplasia is the most common among a group of diseases called chondrodystrophies that affect cartilage as it is Usually mental development is normal in children with Achondroplasia. (Rare skeletal disorders that cause similar characteristics are sometimes associated with mental retardation.) Children with Achondroplasia are usually slow in sitting and walking. This sometimes leads to a false diagnosis of mental retardation. In reality, the slow developmental milestones are usually due to physical causes such as altered body proportions. Occasionally, spinal paralysis causes a lack of motor development. A special developmental chart has been made for children with Achondroplasia. There are also special growth charts for children with Achondroplasia. Charts on development, head circumference, and height follow this discussion. Causes of Achondroplasia A gene called fibroblast growth factor receptor 3 (FGFR3) causes Achondroplasia. About 80% of Achondroplasia cases occur sporadically and are not due to inheritance. In these cases, a gene mutation causes Achondroplasia. There may be a positive correlation between this gene mutation and increased paternal age. In cases caused by gene mutation, there is far less than a 1% risk that siblings will also have Achondroplasia. A genetic work-up on karyotype may help define risk factors.

For more detailed information, contact your health care provider about options that may be available for your specific situation. There are hundreds of reasons why some children never reach expected height as adults. Many are short in stature because of family or ethnic background. Others have a wide variety of medical conditions, many of them genetic, that seriously limit overall growth, or growth of specific parts of the body, such as the limbs or the torso. Some causes of short stature are well-understood and can be corrected, but most are subjects of ongoing research. In some cases, individuals with growth defects are extremely short and have normal body proportions. In other cases, they have abnormal body proportions. Among those with abnormal body proportions, some have arms and legs that are very short while the torso is more nearly normal size. Achondroplasia is the most common growth defect of this type.

Achondroplasia Syndrome This is the genetic variation that produces small bodied people whose bodies differ in proportion to large bodied individuals. The main feature is disproportionate shortening of arms and legs. There are other causes of short stature which are not principally genetic in origin - i.e. do not relate to the FGFR3 site on Human Chromosome 4. Genetic Cause. A single gene variation produces this condition. In 1994 Dr. John Wasmuth and his colleagues found that a variation in the fibroblast growth factor receptor-3 (FGFR3) on Human Chromosome 4 causes achondroplasia. (ref. Human Growth Foundation documentation) 85% of occurrences are by a spontaneous mutation of genetic material. It is inherited as a dominant transferable characteristic, and requires a variant gene from only one parent (heterozygous dominant?).
