Infantile Epileptic Spasms Syndrome Complicating Mosaic Down-Turner Syndrome: A Case Report. [PDF]

open access: yesClin Case Rep
ABSTRACT Severe baseline developmental delays in complex genetic syndromes like Down‐Turner mosaicism can completely mask the psychomotor regression of Infantile Epileptic Spasms Syndrome (IESS). Clinicians must maintain a high index of suspicion and prioritize early video‐EEG screening for any abnormal paroxysmal movements.

High-level mosaic trisomy 21 at amniocentesis in a pregnancy associated with positive NIPT for trisomy 21, prenatal progressive decrease of the trisomy 21 cell line, acute fatty liver of pregnancy and intrauterine fetal death in late gestation

open access: yesTaiwanese Journal of Obstetrics & Gynecology, 2023
Objective: We present high-level mosaic trisomy 21 at amniocentesis in a pregnancy associated with positive non-invasive prenatal testing (NIPT) for trisomy 21, prenatal progressive decrease of the trisomy 21 cell line, acute fatty liver of pregnancy and

Non- Disjunction of Chromosome 21 in the Young Mother at Conception [PDF]

open access: yesPediatric Sciences Journal (Egypt), 2022
Background: Maternal age influences the type of chromosomal anomaly in Down syndrome. The older age is associated with non-disjunction while the younger age is associated with translocation of chromosome 21. Aim of the Work: To study the cytogenetics of

Mosaic Down syndrome and acute lymphoblastic B cell-leukemia. Case report

open access: yesIatreia, 2016
Down syndrome (DS) or trisomy 21 is a constitutional chromosomal abnormality, which may be mosaic in 1 % to 4 % of cases. DS mosaic diagnosis is difficult because most patients have a normal phenotype and show no significant clinical abnormalities ...

Low-level mosaic trisomy 21 at amniocentesis in a pregnancy associated with a negative NIPT result, cytogenetic discrepancy in various tissues, perinatal progressive decrease of the aneuploid cell line and a favorable fetal outcome

open access: yesTaiwanese Journal of Obstetrics & Gynecology, 2023
Objective: We present low-level mosaic trisomy 21 at amniocentesis associated with a favorable fetal outcome. Case report: A 31-year-old primigravid woman underwent non-invasive prenatal testing (NIPT) at 12 weeks of gestation, and the result was normal.

Cytogenetic discrepancy between uncultured amniocytes and cultured amniocytes in mosaic trisomy 15 at amniocentesis

open access: yesTaiwanese Journal of Obstetrics & Gynecology, 2020
Objective: We present mosaic trisomy 15 at amniocentesis. Materials and methods: A 41-year-old woman underwent amniocentesis at 16 weeks of gestation because of an abnormal non-invasive prenatal testing (NIPT) result suspicious of trisomy 15 ...
