In the literature, we found a case report of a patient carrying a 1.69 Mb de novo deletion at 17q11.2 adjacent to NF1 gene, who presented with developmental delay, short stature and dysmorphic features (hypertelorism, flat nasal bridge, and posteriorly rotated and low-set ears), and also with no skin modifications like café-au-lait spots were noted [31]. The gene discussed is NF1; the disease is Global developmental delay.
