Not just carriers: experiences of X-linked female heterozygotes.

PURPOSE: To better understand the needs and experiences of the X-linked carrier community to improve future recognition, diagnosis, and treatment by bringing X-linked carrier voices together. METHODS: An anonymous survey link was distributed to members of Remember the Girls, a non-profit organization for female (XX) carriers of X-linked conditions, through its website, Facebook group, Instagram, and Twitter. The survey was developed to gather data on XX carriers of numerous X-linked conditions. RESULTS: One hundred and fifty individuals participated in the study. The majority (81/150) of individuals learned about their carrier status by giving birth to a son diagnosed with an X-linked condition. However, over 80% (120/145) believed that they should learn this information before the age of 18. Over 80% of participants (124/148) felt that they either have or may have symptoms attributable to their X-linked condition. Yet, only 10.1% (15/148) felt that they had sufficient access to knowledgeable healthcare providers and/or medical information. Additionally, 46.7% (70/150) of participants reported that healthcare providers did not discuss reproductive options with them. Improving carrier access to medical information, research studies, new treatments, and reproductive methods was found to be the top priority. CONCLUSION: Limited information exists on X-linked carriers' risk for symptoms and there is a lack of available treatments. This study demonstrates the need for more knowledgeable healthcare providers and medical information within the X-linked carrier community.

Technology-Driven Noninvasive Prenatal Screening Results Disclosure and Management.

Background: Noninvasive prenatal screening (NIPS) utilization has grown dramatically and is increasingly offered to the general population by nongenetic specialists. Web-based technologies and telegenetic services offer potential solutions for efficient results delivery and genetic counseling. Introduction: All major guidelines recommend patients with both negative and positive results be counseled. The main objective of this study was to quantify patient utilization, motivation for posttest counseling, and satisfaction of a technology platform designed for large-scale dissemination of NIPS results. Methods: The technology platform provided general education videos to patients, results delivery through a secure portal, and access to telegenetic counseling through phone. Automatic results delivery to patients was sent only to patients with screen-negative results. For patients with screen-positive results, either the ordering provider or a board-certified genetic counselor contacted the patient directly through phone to communicate the test results and provide counseling. Results: Over a 39-month period, 67,122 NIPS results were issued through the platform, and 4,673 patients elected genetic counseling consultations; 95.2% (n = 4,450) of consultations were for patients receiving negative results. More than 70% (n = 3,370) of consultations were on-demand rather than scheduled. A positive screen, advanced maternal age, family history, previous history of a pregnancy with a chromosomal abnormality, and other high-risk pregnancy were associated with the greatest odds of electing genetic counseling. By combining web education, automated notifications, and telegenetic counseling, we implemented a service that facilitates results disclosure for ordering providers. Discussion: This automated results delivery platform illustrates the use of technology in managing large-scale disclosure of NIPS results. Further studies should address effectiveness and satisfaction among patients and providers in greater detail. Conclusions: These data demonstrate the capability to deliver NIPS results, education, and counseling-congruent with professional society management guidelines-to a large population.
