The most common types of dwarfism, known as skeletal dysplasias, are genetic. Skeletal dysplasias are conditions of abnormal bone growth that cause disproportionate dwarfism. They include: Achondroplasia. The most common form of dwarfism -- accounting for 70% of cases -- achondroplasia occurs in ...
We describe the prenatal diagnosis of two siblings with microcephalic osteodysplastic primordial dwarfism types I/III at 23 and 26 weeks of gestation, respectively. Early detection by sequential antenatal sonographic evaluation is important for counselling families known to be at risk of this rare ...

1. THE MUNCHKIN BREED AROSE FROM A GENETIC MUTATION. ... The Munchkin's short legs arecaused by an autosomal dominant gene, which causes the long bones in a cat's legs to grow shorter. A cat only needs one copy of the gene to inherit short legs and to pass the trait along to its...
The two main types of dwarfism aredisproportionate dwarfism, where a person has an average-sized trunk and short arms and legs, or shortened trunk and disproportionately long arms and legs, andproportionate dwarfism, where no one body part is too small or too large. (1) ...
The short rib polydactyly syndromes were originally divided into the Majewski and Saldino-Noonan types on the basis of radiologic criteria. He feel that the latter type can be further subdivided into 2 distinct entities. These studies demonstrate that the true heterogeneity of this group of ...
Dwarfism is broadly categorized into two types based on the patient's physical appearance, which are: proportionate short stature (PSS) and disproportionate short stature (DSS). Proportionate short stature (PSS), as the name suggests, means that the limbs and the trunk are proportionately small. ...
However, some types of dwarfism result from the insensitivity of tissues to relatively normal circulating GH levels. The psychotropic effects of GH insufficiency in children are not reported to alter intelligence measures, but a higher incidence of attention deficit disorders, anxiety, depressive mood,...
Dwarfism that is evident prenatally and in the newborn constitutes a small proportion of all the types of dwarfism that occur in children. Though the dwarfism per se is easily recognized on antenatal ultrasound scans, establishing a definitive diagnosis of the type of dwarfism is more difficult an...
