Chromosome Xq28 duplication syndrome

The int22h1/int22h2-mediated Xq28 duplication syndrome is an X-linked intellectual disability syndrome characterized by variable degrees of cognitive impairment typically more severe in males, a wide spectrum of neurobehavioral abnormalities, and variable facial dysmorphic features, Affected males also exhibit a peculiar combination of recurrent sinopulmonary infections and atopy, findings

Xq28 Duplication Syndrome, Int22h1/Int22h2 Mediated

Orphanet: Syndrome de duplication Xq28 proximale

Syndrome génétique rare, lié à l’X, associé à des duplications chromosomiques interstitielles au locus Xq28 comprenant le gène MECP2, Il est caractérisé chez les garçons par une hypotonie précoce, un retard de développement sévère, une déficience intellectuelle, une spasticité progressive, une épilepsie, des symptômes gastro-intestinaux et des infections respiratoires

Xq28 Duplication Syndrome, Int22h1/Int22h2 Mediated

The int22h1/int22h2-mediated Xq28 duplication syndrome is inherited in an X-linked manner, Most affected individuals inherited the duplication from their heterozygous and often asymptomatic mother, However, individuals with de novo duplications have also been identified, Because offspring inh …

Xq28 duplications and microduplications An Xq28 duplication means that the cells of the body have an extra amount of genetic material from one of their 46 chromosomes – the X chromosome, These duplications can be variable in size but those that are too small to be visible under the microscope are called microduplications,

OMIM Entry

Chromosome Xq28 duplication syndrome, 300815, 4, TEXT, A number sign # is used with this entry because this disorder is caused by copy number increase of a small region on distal chromosome Xq28, One report has identified a 0,3-Mb region of Xq28 chrX:153,2-153,5 Mb, NCBI36 containing at least 11 genes and including the GDI1 gene 300104

MECP2 Duplication Syndrome

MECP2 duplication syndrome is caused by the duplication of genetic material on a specific region on the X chromosome Xq28, This region includes the MECP2 gene and typically several adjacent genes, In most affected individuals, the MECP2 duplication is inherited in an X-linked manner; in rare cases, the duplication may occur randomly for no apparent reason de novo duplication,

Le Syndrome de duplication du gène MECP2

Le syndrome de duplication MECP2, un syndrome lié au chromosome X, Cliniquement reconnaissable, le syndrome est provoqué par une anomalie génétique, dans laquelle, il y a une duplication doublé d’un gène appelé MECP2 protéine 2 de liaison méthyle CpG, Le gène de MECP2 est situé sur le chromosome X dans la région Xq28, Les chromosomes sont des structures qui …

Characterizing the phenotypic effect of Xq28 duplication

Individuals with methyl CpG binding protein 2 MECP2 duplication syndrome MDS have varying degrees of severity in their mobility, hand use, developmental skills, and susceptibility to infections, In the present study, we examine the relationship between duplication size, gene content, and overall phenotype in MDS using a clinical severity scale, Other genes typically duplicated within Xq28

Chromosome Xq duplication

Chromosome Xq duplication is a chromosome abnormality that affects many different parts of the body, People with this condition have an extra copy of the genetic material located on the long arm q of the X chromosome in each cell,The severity of the condition and the associated signs and symptoms vary based on the size and location of the duplication; the genes involved; and the sex of …

Xq28 /MECP2 Duplication and Translocation

Xq28 duplication is said to occur when all or part of the Xq region is duplicated, MECP2 duplication is said to occur when the MECP2 gene is duplicated, Some families have been given a diagnosis of Xq28 Duplication Syndrome and some have been given a diagnosis of MECP2 Duplication Syndrome, Although technically these could mean slightly different things, in most cases …

Orphanet: Search a disease

The syndrome is due to Xq28 duplications 4 Mb involving the dosage-sensitive gene MECP2, Diagnostic methods Diagnosis is based on clinical features and is confirmed by array-comparative genomic hybridization techniques or gene-targeted duplication analysis, Differential diagnosis Differential diagnoses include Xq28 functional disomy due to cytogenetically visible rearrangements, …
