The emotional journey of adapting to prenatally identified trisomy X

Article Title: The emotional journey of adapting to prenatally identified trisomy X

Authors: Thompson, Tisher, Davis, Miller, Kirk, Tartaglia, and Howell

Date of Publication: August 19, 2023

“Results suggest providers should carefully consider word choice and timing in delivery of diagnosis, and genetic counseling should provide expectant parents with current research specific to trisomy X, facilitate connections with other parents of young girls with trisomy X, introduce developmental monitoring approaches, and be prepared to support families with a range of emotional responses to the diagnosis and decisions regarding disclosure.”

Recommendations to improve the patient experience and avoid bias when prenatal screening/testing

Article Title: Recommendations to improve the patient experience and avoid bias when prenatal screening/testing

Authors: Meredith, Brackett, Diaz, Freeman, Huggins, Khan, Leach, Levitz, Michie, Onufer, Skotko, Smith, White, Waller, and Ayers

Date of Publication: October 29, 2022

“While prenatal screening and testing have expanded substantially over the past decade and provide access to more genetic information, expectant parents are more likely to describe the diagnosis experience as negative than positive. In addition, the conversations that take place during these experiences sometimes reflect unconscious bias against people with disabilities. Consequently, an interdisciplinary committee of experts, including people with disabilities, family members, disability organization leaders, healthcare and genetics professionals, and bioethicists, reviewed selected published and gray literature comparing the current state of the administration of prenatal testing to the ideal state. Subsequently, the interdisciplinary team created recommendations for clinicians, public health agencies, medical organizations, federal agencies, and other stakeholders involved with administering prenatal screening and testing to create better patient experiences; conduct training for healthcare professionals; create, enforce, and fund policies and guidelines; and engage in more robust data collection and research efforts.”

Positive predictive value of noninvasive prenatal testing for sex chromosome abnormalities

Article Title: Positive predictive value of noninvasive prenatal testing for sex chromosome abnormalities

Authors: Guo, Cai, Lin, Xue, Huang, and Xu

Date of Publication: August 12, 2022

A clinic had 47,855 patients undergo NIPT (noninvasive prenatal testing). They found that the positive predictive value (PPV) for sex chromosome abnormalities was 36.9%. The PPV in patients aged 30–34 years was significantly higher than that in patients aged < 30 years.

Klinefelter Syndrome: What should we tell prospective parents?

Article Title: Klinefelter Syndrome: What should we tell prospective parents?

Authors: White, Zacharin, Fawcett, and McGillivray

Date of Publication: October 12, 2022

“With increasing uptake of antenatal noninvasive prenatal testing (NIPT), a corresponding increase in identification of KS has been documented. Population-based longitudinal data from infancy to adulthood on these individuals is lacking, which impedes balanced antenatal genetic counselling and raises issues for prospective parents and clinicians alike.”
