Distal Xq duplication and functional Xq disomy
Distal Xq duplications refer to chromosomal disorders resulting from involvement of the long arm of the X chromosome (Xq). Clinical manifestations widely vary depending on the gender of the patient and on the gene content of the duplicated segment. Prevalence of Xq duplications remains unknown. About 40 cases of Xq28 functional disomy due to cytogenetically visible rearrangements, and about 50 ...
متن کاملNormal and Self-dual Normal Bases from Factorization of c xq+1 + d xq - ax - b
The present paper is interested in a family of normal bases, considered by V. M. Sidel’nikov, with the property that all the elements in a basis can be obtained from one element by repeatedly applying to it a linear fractional function of the form φ(x) = (ax + b)/(cx + d), a, b, c, d ∈ Fq. Sidel’nikov proved that the cross products for such a basis {αi} are of the form αiαj = ei−jαi+ ej−iαj +γ,...
متن کاملIsochromosome Xq in Mosaic Turner syndrome
A 17-year old female has been referred for karyotyping and genetic counseling. Proband had primary amenorrhea, short stature and poorly developed secondary sexual characteristics. Ultrasound scanning showed hypoplastic uterus and gonadal dysgensis. Chromosomal analysis revealed the mosaic status for the isochromosome formation in the long arm of X, i(Xq). Proband had 3 cell lines. Her karyotype...
متن کاملMolecular and cytogenetic analysis of a familial microdeletion of Xq.
Cytogenetic analysis of a male infant referred for poor neurological development and failure to thrive showed a microdeletion of the X chromosome, his karyotype being 46,Y,del(X)(pter----q21.1:: q21.2----qter). His mother and grandmother were also found to carry the deletion. DNA probes were used to define the deletion molecularly and it was shown to span intervals 2 to 6 of Cremers et al, a po...
متن کاملDifferentially regulated and evolved genes in the fully sequenced Xq/Yq pseudoautosomal region.
Human sex chromosomes, which are morphologically and genetically different, share few regions of homology. Among them, only pseudoautosomal regions (PARs) pair and recombine during meiosis. To better address the complex biology of these regions, we sequenced the telomeric 400 kb of the long arm of the human X chromosome, including 330 kb of the human Xq/YqPAR and the telomere. Sequencing reveal...
