Purpose: Genomic microarrays can detect copy-number variants not detectable by conventional cytogenetics. This technology is diffusing rapidly into prenatal settings even though the clinical implications of many copy-number variants are currently unknown. We conducted a qualitative pilot study to explore the experiences of women receiving abnormal results from prenatal microarray testing performed in a research setting.
Methods: Participants were a subset of women participating in a multicenter prospective study "Prenatal Cytogenetic Diagnosis by Array-based Copy Number Analysis." Telephone interviews were conducted with 23 women receiving abnormal prenatal microarray results.
Results: We found that five key elements dominated the experiences of women who had received abnormal prenatal microarray results: an offer too good to pass up, blindsided by the results, uncertainty and unquantifiable risks, need for support, and toxic knowledge.
Conclusion: As prenatal microarray testing is increasingly used, uncertain findings will be common, resulting in greater need for careful pre- and posttest counseling, and more education of and resources for providers so they can adequately support the women who are undergoing testing.

Background: The impact of ankyloglossia (tongue-tie) on breastfeeding outcomes may be overestimated and surgical treatment in newborns remains a controversial topic. The aim of the present study was to assess and quantify the impact of ankyloglossia in newborns on breastfeeding self-efficacy at 14 days of life.
Methods: A birth cohort study was conducted involving mothers and newborns soon after childbirth at a public hospital in the city of Canoas, southern Brazil.
Objectives: This study aimed to assess the role of olfactory sulci (OS) in diagnosing CHARGE syndrome among fetuses with major congenital heart defects (CHDs).
Methods: We prospectively evaluated OS development in fetuses diagnosed with CHDs from 2017 to 2021. Neurosonography (NSG) was performed using transabdominal and transvaginal approaches after 30 weeks of gestation.

Background: Intrauterine growth restriction (IUGR) is a severe condition in which the fetus fails to reach its genetically predetermined growth potential, impairing prenatal development and predisposing individuals to postnatal consequences that may persist into adulthood. Although fetal mechanisms such as the brain-sparing effect have been proposed to protect the brain against IUGR-related deficits, the extent of this protection remains unclear.
Objective: To conduct a systematic review that demonstrates prenatal morphofunctional abnormalities in the brain of individuals with IUGR.

Chondrodysplasia punctata (CP) is a rare skeletal dysplasia characterized by punctate calcifications in areas of endochondral ossification, with Conradi-Hünermann-Happle syndrome (CDPX2) being the most common form. This study presents a clinical case of a 10-month-old female child, diagnosed with CDPX2 following a referral from a neonatology department of a secondary hospital center to a genetics consultation at a tertiary hospital center in Portugal. Despite normal prenatal monitoring, postnatal evaluations revealed typical manifestations of the syndrome, including nasomaxillary hypoplasia, macrocephaly, and skeletal abnormalities confirmed through imaging.

Background: Hereditary nephropathy is an important cause of renal insufficiency and end-stage renal disease. Therefore, for couples with monogenic nephropathy, preventing transmission of the disease to offspring is urgent. Preimplantation genetic testing for monogenic disorders (PGT-M) is a means to prevent intergenerational inheritance by screening and transplanting normal embryos.
