Chromosome 14q11‐q22 deletion syndrome (OMIM 613457) is a rare contiguous gene syndrome. Two regions of overlap (RO) of the 14q12q21.1 deletion have been identified: a proximal region (RO1), including FOXG1(*164874), NKX2‐1(*600635), and PAX9(*167416) and a distal region (RO2), including NKX2‐1 and PAX9. We report a 6‐year‐old boy with mild dysmorphic facial features, global developmental delay, and hypoplasia of the corpus callosum.
