Interstitial deletions of the long arm of chromosome 12 are rare and only few cases have been reported in literature so far, with different phenotypic features related to size and gene content of deleted regions. Five patients reported a 12q15-q21 deletion, sharing a 1.3 Mb small region of overlap (SRO) and presenting with developmental delay, nasal speech and mild dysmorphic features. We identified by microarray analysis a new case of 12q15 deletion. Our patient clinical features allow the refinement of the SRO to CNOT2, KCNMB4, and PTPRB genes, improving genotype-phenotype correlations.
