Kabuki Syndrome (KS) is a rare genetic syndrome characterized by a typical facial gestalt, variable degrees of intellectual disability, organ malformations, postnatal growth retardation and skeletal abnormalities. So far, KMT2D or KDM6A mutations have been identified as the main cause of KS, accounting for 56-75% and 3-8% of cases, respectively. Patients without mutations in one of the two causative KS genes are often referred to as affected by Kabuki-like syndrome. Overall they represent approximately 30% of KS cases, pointing towards substantial genetic heterogeneity for this condition...

Kabuki syndrome is a rare congenital malformation syndrome characterized by mental retardation, skeletal deformities, auditory dysfunction, cardiac defects, and distinctive facial appearance. Although complex cardiovascular malformations present in early childhood, rarely, atrioventricular septal defects may also present in young adults. Presently described is case of a 22-year-old female with KS who presented with ostium secundum atrial septal defect with deficient rim and idiopathic thrombocytopenic purpura...

Beckwith-Wiedemann syndrome (BWS) is a congenital overgrowth syndrome that is occasionally associated with hyperinsulinemic hypoglycemia (HH) in the neonatal period. Sotos syndrome (SS) and Kabuki syndrome (KS) are other malformation syndromes that may be complicated with HH, however, the detailed clinical characteristics of HH accompanied with these syndromes remain unclear. We herein conducted a nationwide questionnaire survey in Japan. We sent a primary questionnaire concerning the clinical experience for these syndromes to 347 perinatal care institutions...

Kabuki syndrome is a Mendelian intellectual disability syndrome caused by mutations in either of two genes (KMT2D and KDM6A) involved in chromatin accessibility. We previously showed that an agent that promotes chromatin opening, the histone deacetylase inhibitor (HDACi) AR-42, ameliorates the deficiency of adult neurogenesis in the granule cell layer of the dentate gyrus and rescues hippocampal memory defects in a mouse model of Kabuki syndrome (Kmt2d(+/βGeo)). Unlike a drug, a dietary intervention could be quickly transitioned to the clinic...

Choanal atresia is rarely reported in Kabuki syndrome, but is a common feature of CHARGE syndrome. Otherwise, the two conditions have a number of overlapping features, and the molecular links between them have recently been elucidated. Here, we report a case of a mother and her two children who presented with congenital choanal atresia. We performed whole exome sequencing on DNA from the mother and her two unaffected parents, and identified a de novo, novel variant in KMT2D. KMT2D p.Gln3575His segregated with disease status in the family, and is associated with a unique and conserved phenotype in the affected family members, with features overlapping with Kabuki and CHARGE syndromes...

Epidemiological studies, clinical observations, and advances in molecular genetics are contributing to the understanding of the etiology of congenital heart defects (CHDs). Several phenotype-genotype correlation studies have suggested that specific morphogenetic mechanisms put in motion by genes can result in a specific cardiac phenotype. The use of new technologies has increased the possibility of identification of new genes and chromosomal loci in syndromic and non-syndromic CHDs. There are a number of methods available for genetic research studies of CHDs, including cytogenetic analysis, linkage and association studies, copy number variation (CNV) and DNA micro-array analysis, and whole exome sequencing...

Kabuki syndrome is a rare multiple congenital anomaly disorder. Although mental retardation is one of the main features, various neurological symptoms such as hypotonia and seizures can occur. Here we report on a 18-year-old Turkish male patient who was diagnosed previously as Kabuki syndrome. Molecular genetic analysis showed a novel de novo heterozygous mutation (c.12964C > T [p.Gln4322*] ) in the MLL2 gene, that leads to the synthesis of a truncated protein. The aim of the present report is to increase the awareness of Kabuki Syndrome among adult neurologists and to present a previously unreported non-sense mutation in the MLL2 gene...

Most histone methyltransferases (HMTase) harbor a predicted Su(var)3-9, Enhancer-of-zeste, Trithorax (SET) domain, which transfers a methyl group to a lysine residue in their substrates. Mutations of the SET domains were reported to cause intellectual disability syndromes such as Sotos, Weaver, or Kabuki syndromes. Sotos syndrome is an overgrowth syndrome with intellectual disability caused by haploinsufficiency of the nuclear receptor binding SET domain protein 1 (NSD1) gene, an HMTase at 5q35.2-35.3. Here, we analyzed NSD1 in 34 Brazilian Sotos patients and identified three novel and eight known mutations...

BACKGROUND: Smith-Magenis syndrome (SMS) is a developmental disability/multiple congenital anomaly disorder resulting from haploinsufficiency of RAI1. It is characterized by distinctive facial features, brachydactyly, sleep disturbances, and stereotypic behaviors. METHODS: We investigated a cohort of 15 individuals with a clinical suspicion of SMS who showed neither deletion in the SMS critical region nor damaging variants in RAI1 using whole exome sequencing. A combination of network analysis (co-expression and biomedical text mining), transcriptomics, and circularized chromatin conformation capture (4C-seq) was applied to verify whether modified genes are part of the same disease network as known SMS-causing genes...

We report three cases of pilomatricomas associated with Kabuki syndrome (KS), supporting the hypothesis proposed of an association between pilomatricomas and KS and suggesting a noncoincidental association, because the Wnt pathway mutations involved could affect both morphogenesis and tumorigenesis in these patients.

Kabuki syndrome is a clinically and genetically heterogeneous congenital malformation syndrome with protean clinical manifestations. This reflects the important epigenetic role in embryonic development of the two genes currently known to be associated with Kabuki syndrome i.e., KMT2D and KDM6A, which are responsible for Kabuki syndrome 1 and Kabuki syndrome 2, respectively. Hypoglycemia is thought to be a rare manifestation of Kabuki syndrome; however it may be under diagnosed. Herein we describe the case of a 5-year-old girl with Kabuki syndrome 2 in whom persistent hyperinsulinism was diagnosed at 4 years of age...

A 24-year-old woman with a high fever presented at our hospital. She had been diagnosed with Kabuki syndrome at the age of 4 years because she had the typical facial features of the condition ; she had undergone living donor renal transplantation 12 years prior. She was prescribed a course of antibiotics to treat pyelonephritis of the transplanted kidney and the high fever disappeared, but the fever developed again 3 days after the discharge. Abdominal computed tomography revealed a tubular structure of recent onset running from the left dorsal side to the lower part of the bladder...

BACKGROUND/AIMS: Kabuki syndrome is a multiple congenital malformation syndrome with a variety of clinical features including short stature. The cause of this postnatal short stature remains unknown. METHODS: Eighteen children with genetically proven Kabuki syndrome (8 boys and 10 girls; ages 3.3-9.9 years, with a mean of 6.7 years) who underwent growth hormone (GH) stimulation tests were evaluated in a prospective study. Two GH stimulation tests were conducted, including insulin-like growth factor I (IGF-I) and IGF-binding protein 3 (IGFBP-3) serum levels...

Kabuki syndrome (KS) is a rare genetic syndrome characterized by multiple congenital anomalies and varying degrees of mental retardation. Patients with KS often present with facial, skeletal, visceral and dermatoglyphic abnormalities, cardiac anomalies and immunological defects. Mutation of the lysine methyltransferase 2D (KMT2D) gene (formerly known as MLL2) is the primary cause of KS. The present study reported the case of a 4‑year‑old Chinese girl who presented with atypical KS, including atypical facial features, unclear speech and suspected mental retardation...

Kabuki syndrome (MIM 147920) is a well-described, multiple congenital anomaly syndrome characterized by growth and developmental delay, cardiac, renal, and vertebral anomalies, as well as persistent fetal finger pads and distinct facial features. Facies are characterized by long palpebral fissures with eversion of lateral third of the lower eyelid, resembling the "Kabuki make-up" theatre genre after which the syndrome is named. Kabuki syndrome is estimated to affect 1/32,000 births, with 55-80% of patients showing nonsense or frameshift mutations in the KMT2D (MLL2) gene, which encodes a histone transferase located on chromosome 12q...

The genetics of both syndromic (SHL) and non-syndromic hearing loss (NSHL) is characterized by a high degree of genetic heterogeneity. We analyzed whole exome sequencing data of 102 unrelated probands with apparently NSHL without a causative variant in known NSHL genes. We detected five causative variants in different SHL genes (SOX10, MITF, PTPN11, CHD7, and KMT2D) in five (4.9%) probands. Clinical re-evaluation of these probands shows that some of them have subtle syndromic findings, while none of them meets clinical criteria for the diagnosis of the associated syndrome (Waardenburg (SOX10 and MITF), Kallmann (CHD7 and SOX10), Noonan/LEOPARD (PTPN11), CHARGE (CHD7), or Kabuki (KMT2D)...

Kabuki syndrome (KS) is a rare developmental disorder characterized by multiple congenital malformations, postnatal growth retardation, intellectual disability, and recognizable facial features. It is mainly caused by mutations in either KMT2D or KDM6A. We describe a 14-year-old boy with KS presenting with an unusual combination of bilateral microphthalmia with orbital cystic venous lymphatic malformation and neonatal cholestasis with bile duct paucity, in addition to the typical clinical features of KS. We identified the novel KMT2D mutation c...

Kabuki syndrome is a multiple congenital malformation syndrome with a spectrum of clinical features including short stature. Since there is no growth data on Kabuki syndrome patients with a proven KMT2D gene mutation, further research on growth and growth patterns is indicated. Data for this growth study on subjects with Kabuki syndrome were collected from referring clinicians. Subjects were eligible for inclusion in the study if the following criteria were met: a genetically confirmed diagnosis of Kabuki syndrome and no current treatment with growth hormones or other drugs that could influence growth...
