KAT6A syndrome is a rare genetic condition as a result of a mutation in the KAT6A gene. That gene produces the KAT6A protein that is instrumental in DNA packaging and the production of other proteins in the cell. It is an extremely rare condition with only 195 patients around the world currently diagnosed with the condition Discovering the Diagnosis: KAT6A Syndrome Elena was diagnosed with a rare genetic neurodevelopmental disorder called KAT6A syndrome. Her doctor of the past four years, Brittany N. Simpson, MD , director of the Epigenetic Syndromes Clinic, called Wynne to give her the news, explain the disorder and discuss specific treatment options for Elena. From the original 10 cases to the more than 100 diagnosed today, KAT6A kids share a single altered gene that causes neuro-developmental delays, most prominently in learning to walk and talk, plus a spectrum of possible abnormalities involving the head, face, heart, and immune system
Ohdo syndrome, Say-Barber-Biesecker-Young-Simpson variant. More than 10 mutations in the KAT6B gene have been found to cause the Say-Barber-Biesecker-Young-Simpson (SBBYS) variant of Ohdo syndrome. This condition has signs and symptoms that overlap with those of genitopatellar syndrome (described above), although some of the specific developmental abnormalities differ between the two conditions The KAT6A Foundation was created in 2017 & now after that they were working on KAT6A syndrome. After approx 2 year in January 2019 launched the largest-ever study to research KAT6A Gene Mutation that causes KAT6A Syndrome. This foundation helping people with this syndrome & also raising awareness about this rare disorder
Craniosynostosis was found to be one of the characteristics in several KAT6A syndrome patients and in two patients with LoF mutations in KAT6B (Bashir et al., 2017; Tham et al., 2015). Epilepsy was reported in some KAT6A patients (Urreizti et al., 2020), whereas neutropenia is a rare manifestation in KAT6A patients (Kennedy et al., 2018) KAT6A syndrome: news symptoms related to a rare disease. The research team confirmed in five new patients some of the features of the clinical picture related to the pathology, apart from describing new symptoms and affectations in the development of the disease. In particular, the authors overserved new symptoms such as cryptorchidism. KAT6A syndrome is a Mendelian Disorder of the Epigenetic Machinery characterized by intellectual disability and profound expressive language impairment. This study aimed to further characterize behavior and sleep in this syndrome. 26 participants between the ages of 3 and 35 years with KAT6A syndrome were assessed via parental informant using the Adaptive Behavior Assessment System version 3. KAT6A Syndrome has a wide range of symptoms including developmental delays, intellectual disabilities, feeding difficulties, constipation, acid reflux, significant speech and language deficits, vision problems, and hypotonia (weak muscle tone). There are currently no treatment options, and symptoms are treated with medical procedures and.
KAT6A syndrome is an extremely rare genetic neurodevelopmental disorder. It can cause a wide range of symptoms with each child affected differently to the other.

This website provides links to further information on KAT6B for clinicians, scientists, and families. Both syndromes share global developmental delay or intellectual disability, hypotonia, cryptorchidism in males and small or absent patellae. Heart defects, abnormal teeth, deafness, and thyroid problems are common to both syndrome Even among the children and adults who have KAT6A syndrome, a shared diagnosis with countless similarities in the symptoms, every person is different. Some have no verbal communication, like Ruby, while others are able to speak almost normally. Some are entirely wheelchair bound, while others are able to ride bikes, walk, and swim (and even ski)
Conn's syndrome is a rare health problem that occurs when the adrenal glands make too much aldosterone. This problem is also known as primary hyperaldosteronism. Aldosterone is a hormone that controls salt and potassium levels in the blood. Too much leads to high blood pressure Crying combined with miscellaneous gastrointestinal symptoms are typical symptoms of infant with food allergy, but are also common among children with abnormal neurological development. Mutations in KAT6A gene is known to cause a syndrome characterized by developmental delay, hypotonia, cardiac defects, microcephaly, specific facial features and early feeding problems
Since 2015, around 80 cases of syndromic intellectual disability due to mutations at the KAT6A gene have been described in the literature, delineating a new syndrome with variable presentation. An additional subject with a 0.23 MB microdeletion including the entire KAT6A reading frame was identified with genome-wide array comparative genomic hybridization. Finally, by detailed clinical characterization we provide evidence that heterozygous mutations in KAT6A cause a distinct intellectual disability syndrome The diagnosis of KAT6A syndrome is established via recognition of its inherent phenotypic features and the utilization of whole exome sequencing. Thorough craniofacial evaluation is imperative. The results led to the KAT6A syndrome diagnosis. As the change wasn't found in either parent, the results also confirmed that when Daniel's mum gives birth later this year, his new sibling is.
KAT6B disorders include genitopatellar syndrome (GPS) and Say-Barber-Biesecker-Young-Simpson variant of Ohdo syndrome (SBBYSS) which are part of a broad phenotypic spectrum with variable expressivity; individuals presenting with a phenotype intermediate between GPS and SBBYSS have been reported. Both phenotypes are characterized by some degree of global developmental delay / intellectual.
