ABSTRACT Uniparental disomy (UPD) is a rare phenomenon in which both copies of a chromosome are inherited from a single parent. This can lead to genomic imprinting disorders and recessive disorders due to the presence of recessive pathogenic variants in both alleles. Additionally, depending on the mechanisms by which UPD occurs, mosaic aneuploidies may

Patient Perception of Negative Non-Invasive Prenatal Testing Results [PDF]
Non-invasive prenatal testing (NIPT) uses cell-free fetal DNA to assess for fetal aneuploidy during pregnancy. NIPT has higher detection rates and positive predictive values than previous methods; however, NIPT is not diagnostic. Studies suggest patients

ABSTRACT Turner Syndrome (TS) is a sex chromosomal disorder associated with karyotype heterogeneity. Although TS can be associated with severe prenatal findings, most often linked to the 45, X karyotype, the majority of TS fetuses have no overt phenotype, resulting in delayed diagnosis and management.
