Typical dysmorphic features include long palpebral fissures with eversion of the lateral third of the lower eyelid and two or more of the following: 1 arched and broad eyebrows with the lateral third displaying notching or sparseness; 2 short columella with depressed nasal tip; 3 large, prominent or cupped ears; and 4 persistent fingertip pads.

Further criteria for a probable and possible diagnosis, including a table of suggestive clinical features, were included in the publication. Alternatively, it may be discovered using genetic testing whole exome or whole genome sequencing. The fact that some patients do not carry one of the two known mutations or can carry multiple mutations complicates the diagnosis further. Screening[ edit ] Due to its rarity, Kabuki syndrome is not screened for in routine prenatal testing including blood tests , chorionic villus sampling CVS , or amniocentesis.

Although not routine for the general population, if Kabuki syndrome is a specific concern i. However Kabuki syndrome is usually not inherited and therefore most cases do not have a positive family history. They include an echocardiogram ultrasound of the heart for detection of structural heart defects, kidney ultrasound for detection of structural renal abnormalities, immunoglobulin levels, pneumococcal titers and a hearing screening test.

This may include orthopedics such as hip dysplasia , pulmonary sleep study to rule out obstructive sleep apnea due to hypotonia , ophthalmology evaluation vision screen , ENT evaluation hearing evaluation , Neurology evaluation ie if seizures present , Hematology evaluation if bleeding disorder , GI evaluation if gi abnormalities , or others as needed.

There is no specific treatment for Kabuki syndrome. Treatment plans are customized to address the symptoms the individual is experiencing.

Some patients have coexisting conditions which may shorten life expectancy, such as hypoplastic left heart syndrome or kidney dysfunction. It is important that patients with cardiac, renal, or immunologic issues are identified and well-managed.

Never having seen this constellation of symptoms before, Dr Niikawa wondered if he was faced with an undiagnosed condition, a disorder with a genetic basis. Over the next several years, this physician treated several other patients with the same symptoms in his outpatient genetics clinic, furthering support for a disorder never before diagnosed.

A fellow physician at this conference, Yoshikazu Kuroki, recognised the symptoms, and realised that he had also seen several paediatric patients with this presentation; he presented two of his own cases at the second annual conference the following year.

Possible kidney renal abnormalities include malformation or underdevelopment of the kidneys renal dysplasia or hypoplasia , obstruction of the normal flow of urine from the kidneys hydronephrosis and fusion of the kidneys at the base forming a horseshoe shape horseshoe kidneys. Gastrointestinal abnormalities include malrotation of the colon and absence or blockage of the anal opening anal atresia.

Immunological deficiencies have also been reported. Affected females may also experience early onset of breast development premature thelarche , while some males may have undescended testicles cryptorchidism. Some individuals experience rapid weight gain upon puberty. Causes In August of , a group of researchers at the University of Washington reported that mutations in the gene KMT2D formerly MLL2 were responsible for Kabuki syndrome in the majority of affected individuals who were tested.

Most cases of Kabuki syndrome, particularly those caused by mutation of KMT2D, occur for the first time in the affected individual with no family history of the disorder de novo.

Kabuki syndrome

However, familial occurrence of Kabuki syndrome has been reported. The University of Washington researchers confirmed that Kabuki syndrome caused by a dominant mutation in the KMT2D gene can then be passed on to the offspring of an affected individual. Dominant genetic disorders occur when only a single copy of an abnormal gene is necessary for the appearance of the disease.

The abnormal gene can be inherited from either parent, or can be the result of a new mutation gene change in the affected individual de novo. The risk of passing the abnormal gene from affected parent to offspring is 50 percent for each pregnancy regardless of the sex of the resulting child. Variable expressivity means that the disorder expresses itself in dramatically different ways from one person to another.

Most cases of Kabuki syndrome represent new, spontaneous gene mutations that occur with no previous family history. Women typically have two X chromosomes and men typically have one X and one Y chromosome. Women who have a mutation in KDM6A on one X chromosome generally have milder features of Kabuki syndrome compared to males who have a mutation in this gene, although exceptions exist.

However, it is possible for a woman with a mutation in KDM6A to pass on the condition to her children, even if she herself has mild or no symptoms of Kabuki syndrome.

For a woman with a KDM6A mutation, the risk of passing the abnormal gene to her offspring is 50 percent for each pregnancy regardless of the sex of the resulting child. However, female children may have milder or no symptoms of the condition.

An affected male will pass on the abnormal gene to all of his daughters but none of his sons. However, more research is necessary to determine how mutations in these two genes result in the development of the disorder and its associated symptoms. Affected Populations Kabuki syndrome affects males and females in equal numbers.

The incidence of Kabuki syndrome is unknown, but has been estimated to be somewhere between 1 in 32,, individuals in the general population. More than affected individuals have been reported in the medical literature.

Associated Data

Although the disorder was first reported in Japan, Kabuki syndrome has since been reported in a wide variety of different ethnic groups. Related Disorders Features of the following disorders can be similar to those of Kabuki syndrome. Comparisons may be useful for a differential diagnosis. Turner syndrome is a rare chromosomal disorder of females characterized by short stature and the lack of sexual development at puberty.

Among affected females, there is also a heightened incidence of osteoporosis, type II diabetes, and hypothyroidism. There appears to be great variability in the degree to which girls with Turner syndrome are affected by any of its manifestations. Turner syndrome occurs when one of the two X chromosomes normally found in women is missing or incomplete.

Although the exact cause of Turner syndrome is not known, it appears to occur as a result of a random error during the division meiosis of sex cells.

IRF6-related disorders include a spectrum of disorders caused by abnormalities in the interferon regulatory factor 6 IRF6 gene.

Van der Woude syndrome VWS is at the mild end of the spectrum and popliteal pterygium syndrome PPS is at the severe end of the spectrum.

Individuals with VWS can have lip pits alone, cleft lip or cleft palate alone, or a combination of these anomalies. A cone-shaped fold of skin on the nail of the big toe is a very distinctive finding in this condition. Several additional disorders can have certain symptoms or physical findings that are similar to those found in Kabuki syndrome.

However, these disorders usually have other findings that can easily distinguish these disorders form Kabuki syndrome. For more information on these disorders, choose the specific disorder name as your search term in the Rare Disease Database.

Diagnosis Clinical genetic testing for Kabuki syndrome is available. For those families in which X-linked inheritance is suspected, genetic testing for a mutation in KDM6A may be considered first.

Therefore, a clinical diagnosis can be made based upon identification of characteristic findings, a detailed patient history, and a thorough clinical evaluation.

Physicians look for four of the five characteristic findings — distinctive facial features; skeletal abnormalities; intellectual disability; dermatoglyphic abnormalities such as persistent fetal finger pads; and postnatal short stature. Blood tests and chromosomal studies may be used to rule out other disorders.

Standard Therapies Treatment There is no specific treatment for Kabuki syndrome. Treatment is directed toward the specific symptoms that are apparent in each individual. Treatment may require the coordinated efforts of a team of specialists.

Early intervention is important to ensure that children with Kabuki syndrome reach their potential.Disclosure The author reports no conflict of interest in this work. The extent of ID may vary from low-normal to severe 1. Women typically have two X chromosomes and men typically have one X and one Y chromosome.

Kabuki-Make-Up Syndrome with Multiple Congenital Heart Defects

However, it is possible for a woman with a mutation in KDM6A to pass on the condition to her children, even if she herself has mild or no symptoms of Kabuki syndrome. Furthermore, no other copy number variations CNVs of clinical significance were detected in any of the remaining subjects. Skeletal survey revealed spina bifida at T9 and T11 with butterfly vertebra at T10 and T11 and mild scoliosis with concavity toward right.

Diagnosis Clinical genetic testing for Kabuki syndrome is available.

For a woman with a KDM6A mutation, the risk of passing the abnormal gene to her offspring is 50 percent for each pregnancy regardless of the sex of the resulting child. The abnormal gene can be inherited from either parent, or can be the result of a new mutation gene change in the affected individual de novo.

Complications are numerous, sometimes interpenetrating, and early diagnosis of the disease is essential for optimal management.
