MECP2 (methyl CpG binding protein 2) is a gene that encodes the protein MECP2. MECP2 appears to be essential for the normal function of nerve cells. The protein seems to be particularly important for mature nerve cells, where it is present in high levels.
What is Lubs syndrome?
X-linked Lubs-type syndromic intellectual developmental disorder (MRXSL) is a neurodevelopmental disorder characterized by severely to profoundly impaired intellectual development, infantile hypotonia, mild dysmorphic features, poor speech development, autistic features, seizures, progressive spasticity, and recurrent …
What is Microduplication syndrome?
3q29 microduplication syndrome (also known as 3q29 duplication syndrome) is a condition that results from the copying (duplication ) of a small piece of chromosome 3 in each cell. The duplication occurs on the long (q) arm of the chromosome at a position designated q29.
How is duplication syndrome diagnosed?
A diagnosis of MECP2 duplication syndrome is based upon the identification of characteristic symptoms, a detailed patient history, a thorough clinical evaluation and a variety of specialized tests. It should be included in the differential diagnosis of male infants with hypotonia.
How is MECP2 syndrome diagnosed?
A diagnosis of MECP2 duplication syndrome is often suspected based on the presence of characteristic signs and symptoms. Genetic testing can then be ordered to confirm the diagnosis.
What disease is caused by duplication?
DNA Deletion and Duplication and the Associated Genetic Disorders. Deletions and duplications of single-base pairs typically arise during homologous recombination and cause diseases.
How common is duplication syndrome?
The prevalence of MECP2 duplication syndrome is unknown; more than 200 affected individuals have been described in the scientific literature. It is estimated that this condition is responsible for 1 to 2 percent of all cases of intellectual disability caused by changes in the X chromosome.
