چکیده

Interstitial deletions of the long arm of chromosome 4 are rare. The deletions may occur at the proximal or the distal portions of the chromosome and different breakpoints may be involved. We report an interstitial deletion of 4q: 46XY der 4 (q28;q35) in a six-year-old boy with dysmorphic features associated with moderate mental retardation. Parental chromosomal analysis showed a balanced paternal translocation.

Interstitial deletion of the distal long arm of chromosome 4.

We report the first case of an interstitial deletion of the distal long arm of chromosome 4 (q31.22----q34.2). The major clinical features are described and compared to those of other published reports of del 4q, mainly those sharing a common deleted segment with the present case (both interstitial and terminal). This comparison suggests that the characteristic phenotype attributed to terminal ...

Molecular Dissection Using Array Comparative Genomic Hybridization and Clinical Evaluation of An Infertile Male Carrier of An Unbalanced Y;21 Translocation: A Case Report and Review of The Literature

Chromosomal defects are relatively frequent in infertile men however, translocations between the Y chromosome and autosomes are rare and less than 40 cases of Y-autosome translocation have been reported. In particular, only three individuals has been described with a Y;21 translocation, up to now. We report on an additional case of an infertile man in whom a Y;21 translocation was associated wi...

A Patient with Interstitial 5q21 Deletion, Familial Adenomatous Polyposis, Dysmorphic Features, and Profound Neurologic Dysfunction

     Familial adenomatous polyposis (FAP) is a hereditary autosomal dominant cancer syndrome, results from germ line mutation or deletion of the Adenomatous Polyposis Coli (APC) gene on chromosome 5q21. Patients with FAP suffer from multiple polyps mainly at the colorectal region as well as other parts of the gastrointestinal tract, which has propensity to transform into carcinoma. FAP has also...

Balanced Reciprocal Translocation t(X;1) in a Girl with Tall Stature and Primary Amenorrhea

AbstractChromosomal translocations constitute one of the most important, yet uncommon, causes of primary amenorrhea and gonadal dysgenesis. Although X-autosome translocations are frequently associated with streak gonads and clinical features of the Turner syndrome, the majority of X-autosome carriers may present with a variable phenotype, developmental delay, and recognizable X-linked syndrome ...

Partial trisomy 2q(2q37.3-->qter) and monosomy 7q(7q34--->qter) due to paternal reciprocal translocation 2;7: a case report.

We report an unbalanced translocation involving chromosome 2 and 7 due to a balanced reciprocal translocation 2;7 in the father. The female fetus had a partial trisomy of the long arm of chromosome 2 with a partial monosomy of distal 7q. Ultrasound at the first trimester had indicated normal fetal anatomy, including normal intracranial structures. Parental karyotypes showed a paternal balanced ...
