Kabuki syndrome (KS) (Kabuki make-up syndrome, Niikawa-Kuroki syndrome) is a rare genetic disorder first diagnosed in 1981. Kabuki make-up syndrome (KMS) is a multiple malformation/intellectual disability syndrome that was first described in Japan but is now reported in many other ethnic groups. KMS is characterized by multiple congenital abnormalities: craniofacial, skeletal, and dermatoglyphic abnormalities; intellectual disability; and short stature. Other findings may include: congenital heart defects, genitourinary anomalies, cleft lip and/or palate, gastrointestinal anomalies including anal atresia, ptosis and strabismus, and widely spaced teeth and hypodontia. The KS is associated with mutations in the MLL2 gene in some cases were also observed deletions of KDM6A. This study describes three children with autism spectrum disorders (ASDs) and KS and rehabilitative intervention that must be implemented.

Say-Barber/Biesecker/Young-Simpson syndrome (SBBYSS; OMIM 603736) is a rare syndrome with multiple congenital anomalies/malformations. The clinical diagnosis is usually based on a phenotype with a mask-like face and severe blepharophimosis and ptosis as well as other distinctive facial traits. We present a girl with dysmorphic features, an atrial septal defect, and developmental delay. Previous genetic testing (array-CGH, 22q11 deletion, PTPN11 and MLL2 mutation analysis) gave normal results. We performed whole-exome sequencing (WES) and identified a heterozygous nonsense mutation in the KAT6B gene, NM_001256468.1: c.4943C>G (p.S1648*). The mutation led to a premature stop codon and occurred de novo. KAT6B sequence variants have previously been identified in patients with SBBYSS, and the phenotype of the girl is similar to other patients diagnosed with SBBYSS. This case report provides additional evidence for the correlation between the KAT6B mutation and SBBYSS. If a patient is suspected of having a blepharophimosis syndrome or SBBYSS, we recommend sequencing the KAT6B gene. This is a further example showing that WES can assist diagnosis.
