Objective:We present prenatal diagnosis of maternal uniparental disomy (UPD) 21 in association with low-level mosaic trisomy 21at amniocentesis in a pregnancy associated with intrauterine growth restriction (IUGR) and a favorable outcome. Case report:A 42-year-old, gravida 2, para 0, woman ...
We present low-level mosaic trisomy 13 at amniocentesis associated with a favorable outcome in a pregnancy. Case report A 39-year-old woman underwent amniocentesis at 17 weeks of gestation because of advanced maternal age. Amniocentesis revealed a karyotype of 47,XY,+13[8]/46,XY[20]. The wo...
(e) NGS and (f) CMA results show consistent mosaic trisomy 2 (percentage: 40–50%) in sample 14S1003400. In a and c, black lines indicate the distribution of copy ratios for adjusted nonoverlapping windows (5 kb), and orange lines indicate the distribution of increment rate of coverage...
To further examine the differences in amplification of senescent cells vs proliferating cells we performed qPCR as listed above on 10 more proliferating and senescence single cells as well as five trisomy 21 cells. A student’s t-test was used to determine significant differences at each cycle bet...
Background A discrepancy between the fetal karyotype and the appearance of genitalia on ultrasound can be a diagnostic challenge. In these cases, it is difficult to shorten the extensive list of differential diagnoses without information on internal anat
The correlation between the percentage of mosaicism and the severity of the phenotype in mosaic trisomy 21 has been determined in previous studies. Patients with low percent of trisomy 21 have less phenotypic manifestations, higher IQs, and better overall survival. We report on a 1-day-old baby...
