Postpartum Breast Cancer and Survival in Women With Germline BRCA Pathogenic Variants
(Posted Apr 21, 2024 8AM)

From the article: "Is postpartum diagnosis an independent risk factor associated with mortality among patients with young-onset breast cancer with germline BRCA1/2 pathogenic variants (PVs)? Findings: This cohort study including 903 women with BRCA germline PVs found that a breast cancer diagnosis less than 10 years post partum was associated with higher risk of mortality compared with nulliparous women and women diagnosed at least 10 years post partum. Increased risk after childbirth varied, with highest risk at less than 5 years for women with ER-positive breast cancer vs 5 to less than 10 years for women with ER-negative breast cancer, and BRCA1 carriers had peak risk of mortality 5 to less than 10 years post partum, with no associations observed for BRCA2 carriers. Meaning: These findings suggest that a breast cancer diagnosis within 10 years of childbirth was independently associated with increased risk for mortality in patients with germline BRCA1/2 PVs, especially for carriers of BRCA1 PVs."

Impact of Race, Socioeconomic Status, and Geography on Healthcare Outcomes for Children With Sickle Cell Disease in the United States: A Scoping Review
(Posted Apr 19, 2024 10AM)

From the abstract: "A large proportion of patients with sickle cell disease (SCD) identify as Black or African American (AA). Social bias and stigma in healthcare outcomes for children with SCD are impossible to explore without considering the impact of racial/cultural identity, socioeconomic status (SES), and geography. It is important to understand the current influences of social movements, expanded health insurance coverage, and telehealth on these variables when considering healthcare outcomes for patients with SCD.

Assessing the Benefits and Harms Associated with Early Diagnosis from the Perspective of Parents with Multiple Children Diagnosed with Duchenne Muscular Dystrophy
O Battacharria et al, IJNS, April 15, 2024 (Posted Apr 15, 2024 2PM)

From the abstract: " Duchenne muscular dystrophy (DMD) is a rare neuromuscular disorder diagnosed in childhood. Limited newborn screening in the US often delays diagnosis. With multiple FDA-approved therapies, early diagnosis is crucial for timely treatment but may entail other benefits and harms. Using a community-based survey, we explored how parents of siblings with DMD perceived early diagnosis of one child due to a prior child’s diagnosis. We assessed parents’ viewpoints across domains including diagnostic journey, treatment initiatives, service access, preparedness, parenting, emotional impact, and caregiving experience."

Toward clinical exomes in diagnostics and management of male infertility
C Lillepea et al, AJHG, April 15, 2024 (Posted Apr 15, 2024 2PM)

From the abstract: "Infertility, affecting ~10% of men, is predominantly caused by primary spermatogenic failure (SPGF). We screened likely pathogenic and pathogenic (LP/P) variants in 638 candidate genes for male infertility in 521 individuals presenting idiopathic SPGF and 323 normozoospermic men in the ESTAND cohort. Molecular diagnosis was reached for 64 men with SPGF (12%), with findings in 39 genes (6%). The yield did not differ significantly between the subgroups with azoospermia (20/185, 11%), oligozoospermia (18/181, 10%), and primary cryptorchidism with SPGF (26/155, 17%). "
