Many patients with Angelman syndrome experience epileptic seizures. (2007) identified a de novo heterozygous nonsense mutation in the SATB2 gene (R239X; 608148.0001). A syndrome that has material basis in genetic changes that affect the SATB2 gene and that is characterized by mild to severe intellectual disability, a delayed or absent ability to speak, severe speech anomalies, abnormalities of the palate, teeth anomalies, behavioral issues with or without bone or brain anomalies, and onset before age 2. Frequency: As of 2020, ~300 people have been diagnosed with this syndrome. (2014) identified a de novo heterozygous intragenic duplication of the SATB2 gene (608148.0002). Clinical and molecular consequences of disease-associated de novo mutations in SATB2. A medical professional will take a blood or spit sample and then look for specific changes in the persons DNA to confirm the CdLS diagnosis. Alterations to the SATB2 gene can result from different mechanisms, such as contiguous deletions (missing pieces of the chromosome 2 that include the SATB2 gene and other genes that are close together), duplications (extra pieces of genetic material) translocations (rearrangements involving the gene), or point genetic changes (a genetic change that only affects a single nucleotide of the DNA).". Genet Med. Most people with Angelman syndrome live nearly as long as people without the condition, however, they are unable to live independently and will need life-long supportive care.

The condition also has several possible physical symptoms, including: People often do not report mild cases of CdLS, which means that people may underestimate its prevalence. [PubMed: 21295280] The term "life expectancy" refers to the number of years a person can expect to live. Am. Glass syndrome, also known as SATB2-associated syndrome (SAS), is a recently described syndrome characterized by developmental delay/intellectual disability with absent or limited speech development, craniofacial abnormalities including palatal and dental abnormalities, behavioral problems, and dysmorphic features. The Edwards syndrome or trisomy 18 is characterized by a large number of clinical pictures, which are: There is a delay in development, both in the prenatal and postnatal stages. Osteogenesis imperfecta (OI) is an inherited (genetic) bone disorder that is present at birth. Individuals with mild Hunter syndrome also have a shortened lifespan, but they typically live into adulthood and their intelligence is not affected. 65: 387-396, 1999. Learn more here. It occurs as a result of changes in DNA sequences, which affect the production of certain proteins. Some of the common features can be . Hum. The cleft or high-arched palate most likely resulted from hemizygosity for the SATB2 gene (608148).

Mutat. About half of affected individuals have abnormalities in the structure of the brain.The most common craniofacial anomalies in people with SATB2-associated syndrome are a high arch or an opening in the roof of the mouth (high-arched or cleft palate), a small lower jaw (micrognathia), and dental abnormalities, which can include abnormally sized or shaped teeth, extra (supernumerary) teeth, or missing teeth (oligodontia). In 2007, on average, persons with Down syndrome lived to be about 47 years old. The syndrome is present in around 1-16 out of 100,000 adults. One female X chromosome is typically inactive, which means the genes on that chromosome do not function. Cornelia de Lange syndrome (CdLS) is a rare genetic condition that can affect multiple organs.

Whole genome sequencing of 45 Japanese patients with intellectual disability. Severe combined immunodeficiency (SCID) is a group of rare disorders caused by mutations in different genes involved in the development and function of infection-fighting immune cells. In some people, CdLS is autosomal dominant. Some of these include: Despite the strong evidence supporting an important role for SATB2 in palatal development, mutation analysis of an additional 70 unrelated patients with isolated cleft palate did not reveal any coding region variants.
