Kabuki syndrome (KS) is an epigenetic machinery multisystem disorder with peculiar facial gestalt and dental-oral anomalies. This report describes the case of a KS patient with congenital hyperinsulinism, growth hormone deficiency and novel heterogenous missense mutations in exon 25 of the KDM6A (c.3715T>G, p.Trp1239Gly) and exon 1 of the ABCC8 (c.94A>G, p.Asn32Asp) genes. She presented with solitary median maxillary central incisor (SMMCI) and mandibular incisor hypodontia, which could be a unique dental manifestation in KS 2.
