summary

What is the cause of the baby's finger?

The main cause of polydactyly is the influence of environmental factors during pregnancy on the process of embryo development, such as some drugs or pregnant women with viral infection, trauma, radioactive material stimulation, etc. In addition, smoking during pregnancy, exposure to agricultural chemicals during pregnancy, and occupational exposure to harmful substances before pregnancy will increase the risk of fetal polydactyly.

Secondly, gestational diabetes mellitus also increases the risk of fetal polydactyly. Improving maternal diet has a certain role in the prevention of polydactyly.

The main reason of polydactyly is that the embryo base of limb bud is damaged at the early stage of differentiation. It is caused by the abnormal development of the apical ridge of the ectoderm, the extension of the lateral apex of the thumb to the proximal position and the slow retraction. Another part of polydactyly is due to genetic factors. About two-thirds of polydactyly have a family history, and there will be a family history of intergenerational inheritance.
