A newborn baby, from the first normal pregnancy, showed the absence of nails on three fingers of the right hand. Instead, there is a thin skin on the nail beds. What pathology is this? What is it connected with?

Aplasia of the nails of three fingers is associated with a congenital malformation of the nails. Probably, the change in cell induction led to impaired proliferation and keratinization of the epithelium of the nail plate. It is possible that the cause of this developmental anomaly was a violation of the proliferation and differentiation of the cells of the nail plate.
