Interstitial 1p deletions are rare events. Very few cases of 1p31.1p31.3 deletions characterized by variable phenotypes have been reported. No clear genotype-phenotype correlation has been determined yet. We present a child with a de novo interstitial 1p31.1p31.3 deletion, identified by array CGH, associated with intellectual disability and severe language impairment. The deleted region contains 20 OMIM genes, but we focused on GADD45A (MIM 126335; growth arrest- and DNA damage-inducible gene), LRRC7 (MIM 614453; leucine-rich repeat-containing protein 7), and NEGR1 (MIM 613173; neuronal growth regulator 1). We discuss whether these genes play a role in determining the phenotype of our patient in order to investigate the possibility of a genotype-phenotype correlation.
