Síndromes muy poco frecuentes

Abstract

In an attempt to facilitate the knowledge of the malformation syndromes that have very few frequencies to pediatricians and first health care physicians, particularly to those of rural areas, we have selected six new syndromes. As in previous years, the syndromes are selected from the ECEMC database registry. In this Boletín we include the following syndromes: Townes-Bröcks, MMT, Smith-Lemli-Opitz, Coffin-Siris, Espleno-gonadal fusion, and Silver-Russell syndromes. For each syndrome, we described the most important clinical characteristics, and the present knowledge of their causal factors.
