See More. Through its interactions with these proteins, pericentrin plays a role in regulation of the cell cycle , which is the cell's way of replicating itself in an organized, step-by-step fashion.
PCNT gene mutations lead to the production of a nonfunctional pericentrin protein that cannot anchor other proteins to the centrosome. As a result, centrosomes cannot properly assemble microtubules, leading to disruption of the cell cycle and cell division. Impaired cell division causes a reduction in cell production, while disruption of the cell cycle can lead to cell death.
This overall reduction in the number of cells leads to short bones, microcephaly, and the other signs and symptoms of MOPDII.
This condition is inherited in an autosomal recessive pattern , which means both copies of the gene in each cell have mutations. The parents of an individual with an autosomal recessive condition each carry one copy of the mutated gene, but they typically do not show signs and symptoms of the condition.

Microcephalic osteodysplastic primordial dwarfism type II. From Genetics Home Reference. This involves multiple procedures. Because of the risk and stress involved, parents often wait until the child is older before trying it. Primordial dwarfism can be serious, but it is very rare.
Not all children with this condition live on to adulthood. Advances in gene therapies hold the promise that treatments for primordial dwarfism may someday become available.
Making the best of the time available can improve the well-being of your child and others in your family. Consider checking out the medical information and resources on dwarfism offered through Little People of America. It's true that I can't be independent in all senses of the word, but maybe I need to continue looking for ways in which I can.
French researchers fool a dysfunctional gene to stimulate regular bone growth in young mice with dwarfism. The short answer? You should eat foods that energize you and make you feel good about yourself and your body.
