In most cases, this common type of short-limbed dwarfism is related to a genetic mutation in the fibroblast growth factor receptor 3 gene. There are two possible causes of achondroplasia. One possible cause is a genetic mutation in the fibroblast growth factor receptor 3 (FGFR3) gene located on chromosome 4.The other possible cause is that the condition can be inherited from a parent with achondroplasia.chondroplasia can also be inherited in an autosomal dominant pattern, which means that one copy of the altered gene in each cell is sufficient to cause the disorder. In these cases, one of the parents with achondroplasia passes on the FGFR3 gene to the child.
A majority of the women who contracted Zika in the first or second trimester were still pregnant at the time of the report in early April. Other research has found that pregnant women infected with the Zika virus during their first trimester face as high as a 13 percent chance that their fetus will develop microcephaly.
