Achondrogenesis is a number of disorders that are the most severe form of congenital chondrodysplasia (malformation of bones and cartilage). These conditions are characterized by a small body, short limbs, and other skeletal abnormalities. As a result of their serious health problems, infants with achondrogenesis are usually born prematurely, are stillborn, or die shortly after birth from respiratory failure. Some infants, however, have lived for a while with intensive medical support.
Researchers have described at least three forms of achondrogenesis, designated as Achondrogenesis type 1A, achondrogenesis type 1B and achondrogenesis type 2. These types are distinguished by their signs and symptoms, inheritance pattern, and genetic cause. Other types of achondrogenesis may exist, but they have not been characterized or their cause is unknown.
Achondrogenesis type 1A is caused by a defect in the microtubules of the Golgi apparatus. In mice, a nonsense mutation in the thyroid hormone receptor interactor 11 gene (Trip11), which encodes the Golgi microtubule-associated protein 210 (GMAP-210), resulted in defects similar to the human disease. When their DNA was sequenced, human patients with achondrogenesis type 1A also had loss-of-function mutations in GMAP-210. GMAP-210 moves proteins from the endoplasmic reticulum to the Golgi apparatus. Because of the defect, GMAP-210 is not able to move the proteins, and they remain in the endoplasmic reticulum, which swells up. The loss of Golgi apparatus function affects some cells, such as those responsible for forming bone and cartilage, more than others.[1]
Achondrogenesis type 1B is caused by a similar mutation in SLC26A2, which encodes a sulfate transporter.

- Pathologic diagnosis of achondrogenesis type 2 in a fragmented fetus: Case report and differential diagnostic approach.
- Weisman PS, Kashireddy PV, Ernst LM.Author information a Northwestern Memorial Hospital, Pathology.AbstractAbstract The lethal genetic skeletal disorders (GSDs) are a group of GSDs that, by definition, usually result in death in utero or within the perinatal period. As the lethal GSDs are often ultrasonographically detectible by the early midtrimester, dilation and evacuation (D&E) is the method of choice for elective termination of pregnancy in many institutions. However, as the diagnosis of the lethal GSDs relies heavily upon radiologic examination of fetal remains, reaching an accurate diagnosis in this setting can be challenging. We report an autopsy case of a fetus delivered by D&E at 15 4/7 weeks gestation with radiologic, histologic, and genetic findings compatible with achondrogenesis type 2 and discuss an evidence based differential diagnostic approach to lethal GSDs terminated by early midtrimester D&E.

ACG1A is caused by mutations in the TRIP11 gene, resulting in deficiency of the Golgi microtubule associated protein 210. In this study we describe dizygotic twins with a clinical and radiological phenotype of ACG1A who were homozygous for a novel nonsense mutation in the TRIP11 gene. In addition, another patient with a milder manifestation, not readily distinguishable from those of other lethal skeletal dysplasias, was found to be a compound heterozygote for a nonsense mutation and a deletion of the 3' end of the TRIP11 gene. We conclude that mutations of the TRIP11 gene may encompass a wider phenotypic range than previously recognized.
