Trisomy 15

Duplication of Chromosome 15

Patients also present brain (e.g. hypoplastic cerebellum, ventricular asymmetry), renal (e.g. small dysplastic kidneys), and/or genital (undescended testis, small penis, hypoplastic labia majora) anomalies. [orpha.net]

Because the triplo-X and the trisomy 15 were present in different cell lines, gain of an X chromosome occurred either in the same cell division as the trisomy 15 rescue or shortly before or after. [lirias.kuleuven.be]

The present case provides evidence for cytogenetic discrepancy between uncultured and cultured amniocytes in mosaic trisomy 15 at amniocentesis. [mendeley.com]

For pregnancies that progress to delivery, two forms of trisomy 15 syndrome are usually present in the children born: Prader-Willi syndrome (PWS) and Angelman syndrome (AS). [wisegeek.com]

  • Coarctation of the Aorta

    Prenatal diagnosis and molecular cytogenetic characterization of de novo partial trisomy 12q (12q24.21 qter) and partial monosomy 6q (6q27 qter) associated with coarctation of the aorta, ventriculomegaly and thickened nuchal fold. [pediatricneurosciences.com]

  • Aspiration

    In some cases, swallowing and feeding difficulties may cause food to be inhaled (aspirated) into the lungs, which may result in severe lung infections (aspiration pneumonia). [rarediseases.org]

  • Failure to Thrive

    Such feeding and swallowing difficulties may result in or contribute to an affected infant’s failure to grow or gain weight at the expected rate (failure to thrive). [rarediseases.org]

    Finally, patient 3 had IUGR, failure to thrive, mental and psychomotor retard, café-au-lait patches. We reviewed 96 patients with chromosome 15q duplication and we summarized the main clinical features in Table 1. [ec.bioscientifica.com]

  • Flexion Contracture

    In some cases, abnormalities involving the joints, tendons, muscles, and bones (e.g., flexion contractures, malformations of the fingers and/or toes, scoliosis) may be treated with orthopedic techniques potentially in combination with surgery. [rarediseases.org]

  • Dolichocephaly

    In some cases, the fibrous joints between certain bones in the skull (sagittal sutures) close prematurely (craniosynostosis), causing the head to appear abnormally long and narrow (dolichocephaly). [rarediseases.org]

  • Antimongoloid Slant

    Distinctive craniofacial features may include microcephaly, antimongoloid slant, epicanthal folds, micrognathia, flattened nasal bridge, long philtrum, puffy cheeks and high arched palate. [4], [5], [6], [7] Other abnormalities may include hypotonia, [pediatricneurosciences.com]

  • Profound Mental Retardation

    In addition, most affected infants and children have severe to profound mental retardation. However, in rare cases (i.e., trisomy 15q25-qter), only mild mental retardation may be present. [rarediseases.org]

  • Encephalopathy

    There was no history of seizures, encephalopathy, or jaundice in the neonatal period. He developed social smile at 3 months, and was recognizing his mother and reaching out for objects at the time of presentation. [pediatricneurosciences.com]

Additional abnormalities may involve malformation of the skeleton, spine and neck ; fingers and/or toes ; genitals (particularly in males); and, in some cases, heart problems. [1] [2] Treatment Edit The condition is incurable and treatment is based on [en.m.wikipedia.org]

Poor pregnancy outcome prognosis is associated with the presence of aneuploid cells, and there is also a risk of uniparental disomy 15 (UPD15) due to correction of the trisomic state to a disomic constitution. [docksci.com]

In the absence of any positive findings in these follow-up tests the prognosis for pregnancy outcome is very good. Trisomy 15 detected on amniocentesis Hsu et al. (1997) summarized 11 cases of trisomy 15 mosaicism detected at amniocentesis. [mosaicism.bcchr.ca]

The current genetic epidemiology is based on western populations, according to which 15q11.2-q13 paternal deletion is responsible for 70–75%, maternal UPD for 25–28%, and ID for 2–5% of the cases of PWS ( 16 – 18 ). [spandidos-publications.com]
