1 Two different mutations in the FGFR3 gene cause more than 99 per cent of cases of achondroplasia. 2  It is a dominant genetic disease so only one copy of the FGFR3 gene needs to be mutated for symptoms to develop. 3  Achondroplasia can be inherited from a parent with the disease.chondroplasia is a genetic disorder affecting bone development that results in short-limb dwarfism. 1  Achondroplasia is the most common form of short-limb dwarfism, a disorder in which bone tissue does not develop properly, especially the long bones of the arms and legs.

In Brazil, the viral infection has been linked to birth defects (mainly small head and small brain size, termed microcephaly) in babies (newborns) whose mothers became infected with Zika virus during their pregnancy.
Zika virus (or Zika) has been reported in Cuba. Public health officials have reported that mosquitoes in Cuba are infected with Zika and spreading it to people. Many people infected with Zika virus do not get sick or only have mild symptoms. However, infection during pregnancy can cause severe birth defects.
