How many cases of primordial dwarfism are there?
How common is primordial dwarfism? Little is known concerning the incidence. We estimate that there are around 100 individuals in the United States and Canada, giving a rough estimate of 1 in 3 million.
How is primordial dwarfism inherited?
All types of microcephalic osteodysplastic primordial dwarfism (MOPD) appear to be inherited in an autosomal recessive manner. This means that affected individuals have abnormal gene changes ( mutations ) in both copies of the disease-causing gene, with one copy inherited from each parent.
Who is the oldest person with primordial dwarfism?

Can primordial dwarfs get pregnant?
Although in the past 50 years there have been many case reports of successful pregnancies in these conditions, these have been mainly in women with disproportionate dwarfism who have relatively well preserved trunk height and organ proportions, and therefore a more favourable prognosis for pregnancy.
What is the life expectancy of a primordial dwarf?
It is rare for individuals affected by primordial dwarfism to live past the age of 30. In the case of microcephalic osteodysplastic primordial dwarfism type 2 (MOPDII), there can be increased risk of vascular problems, which may cause premature death.
Who is the oldest living primordial dwarf?

Can one identical twin be a dwarf?

Are there any primordial dwarfs in the world?
Primordial dwarfism is one of the rarer forms of dwarfism in the world. People with primordial dwarfism tend to be much smaller than any other dwarfs. In fact, several of the people on this list have been recognized by Guinness World Records for being the shortest man or woman in the world.
What causes short stature in people with primordial dwarfism?
Typically, people with primordial dwarfism are born with very low birth weights. After birth, growth continues at a much slower rate, leaving individuals with primordial dwarfism perpetually years behind their peers in stature and in weight. Most cases of short stature are caused by skeletal or endocrine disorders.
Are there any effective treatments for primordial dwarfism?
The five subtypes of primordial dwarfism are among the most severe forms of the 200 types of dwarfism. There are as yet no effective treatments for primordial dwarfism.
What is the role of Pericentrin in primordial dwarfism?
Pericentrin has a role in cell division, proper chromosome segregation and cytokinesis . Another gene that has been implicated in this condition is DNA2. Mutations in this gene have been implicated in Seckel syndrome. Since primordial dwarfism disorders are extremely rare, misdiagnosis is common.
