Non-invasive prenatal testing (NIPT) has grown in ubiquity in the last decade and is now endorsed by Society for Maternal Fetal Medicine and American College of Obstetricians and Gynecologists as a screening tool for aneuploidy in all patients. Past studies have demonstrated a tendency among obstetrics patients to focus on the ability of NIPT to predict fetal sex chromosomes; however, data on the experiences of genetic counselors (GCs) counseling on NIPT and fetal sex prediction are limited. This mixed-methods study aimed to explore how GCs counsel about NIPT and fetal sex prediction, as well as the use of gender-inclusive language in this setting.

Objective: To evaluate the utility of postnatal genetic testing on umbilical cord blood (CB) for prenatally identified high-probability fetuses.

Method: CB for genetic testing was offered to individuals who met one of the following criteria: (i) fetal anomaly, (ii) positive non-invasive prenatal screening by cfDNA or biochemical analysis, or (iii) family history. Individuals with diagnostic testing, but not microarray, were also included when recommended by society guidelines.

Objective: To investigate the efficacy and outcomes of chromosomal microarray (CMA) in the cytogenomic evaluation of products of conception (POC).

Method: Over a 42-month period, 323 POC samples were tested by CMA. Results were assessed using variables including phenotype, gestational age, results from orthogonal testing, and follow-up parental analysis.

Background: Although clinician, researcher, and patient resources for matchmaking exist, finding similar patients remains an obstacle for rare disease diagnosis. The goals of this study were to develop and test the effectiveness of an Internet case-finding strategy and identify factors associated with increased matching within a rare disease population.

Methods: Public web pages were created for consented participants.

Purpose: Copy-number variant (CNV) assessment is recommended for patients undergoing prenatal diagnostic testing. Noninvasive screening tests have not been extensively validated for CNV detection. The objective of this study was to compare the ability of genome-wide noninvasive prenatal screening (NIPS) to chromosomal microarray to detect clinically significant findings.

Genetic results have implications not only for the individual, but also for their family members. Research on family communication of genetic results has primarily focused on families affected by adult-onset, dominant conditions as well as more common genetic conditions such as familial hypercholesterolemia, cardiomyopathies, and genetic hearing loss. This study therefore aimed to characterize genetic result communication in families with rare and undiagnosed conditions and identify factors that influence communication.

Cervical cancer rates in low- and middle-income countries (LMICs) are higher than in developed countries and account for 80% of an estimated 500,000 new cases annually. Factors that contribute to this are that diagnostic and prevention strategies designed for developed countries suffer from the combination of low vaccination rates and limitations due to lack of consistent access to both healthcare and supplies. Here we: 1) improve upon our LMIC deployable HPV test and 2) determine both the high and low-risk HPV genotype prevalence in an isolated Honduran population.
