Trisomy 21 consistently activates the interferon response
Although it is clear that trisomy 21 causes Down syndrome, the molecular events acting downstream of the trisomy remain ill defined. Using complementary genomics analyses, we identified the interferon pathway as the major signaling cascade consistently ...

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

A multicenter study of fetal chromosomal abnormalities in Chinese women of advanced maternal age [PDF]
ObjectiveThis study aimed to determine the rates of different fetal chromosomal abnormalities among women of advanced maternal age in China and to discuss the possible misdiagnosis risks of newer molecular techniques, for selection of appropriate ...

False negative NIPT results: Risk figures for chromosomes 13,18 and 21 based on chorionic villi results in 5967 cases and literature review [PDF]
Non-invasive prenatal testing (NIPT) demonstrated a small chance for a false negative result. Since the "fetal" DNA in maternal blood originates from the cytotrophoblast of chorionic villi (CV), some false negative results will have a biological origin ...

Ageing and Olfactory Dysfunction in Trisomy 21: A Systematic Review
Purpose: The olfactory system is particularly vulnerable in an ageing brain, both anatomically and functionally, and these brain changes are more pronounced among individuals with trisomy 21.

Clinical findings associated with a de novo partial trisomy 10p11.22p15.3 and monosomy 7p22.3 detected by chromosomal microarray analysis. [PDF]
We present the case of an 18-month-old boy with dysmorphic facial features, developmental delay, growth retardation, bilateral clubfeet, thrombocytopenia, and strabismus, whose array CGH analysis revealed concurrent de novo trisomy 10p11.22p15.3 and ...

Objective: We present prenatal diagnosis of maternal uniparental disomy (UPD) 21 in association with low-level mosaic trisomy 21 at amniocentesis in a pregnancy associated with intrauterine growth restriction (IUGR) and a favorable outcome.

Background: Chromosomal aneuploidy due to meiotic non-disjunction is among the most significant and common causes of miscarriages in humans. The present study was conducted to investigate the presence of fetal trisomy 13, 18, and 21 in Pakistani ...
