[Bilateral symmetrical nail hypoplasia of the hands].

We present the case of a 15-month-old boy who was brought by his mother for lesions affecting the nails of the first 3 fingers of both hands, and that had been present since birth. The other fingernails and the toenails showed no abnormalities. The patient had started walking at 1 year, with abnormalities of gait and frequent falls. In addition, the child had started speaking late, at 12 months of age, saying only individual words at the age of 15 months. The mother stated that her other daughter and several members of the paternal family had similar abnormalities of the nails, also associated with gait disturbances (Figure 1).
