Insights

Parents prefer full disclosure or making their own decisions regarding newborn screening results for conditions like cystic fibrosis (CF) and related syndromes. They value information and autonomy, even if it causes distress.

Area of Science:

  • Genetics and Genomics
  • Public Health
  • Pediatrics

Background:

  • Newborn screening (NBS) identifies genetic conditions in infants.
  • Incidental findings in NBS, such as cystic fibrosis (CF) carrier status, CFTR-related metabolic syndrome (CRMS), and CFSPID, pose disclosure challenges.
  • Parental preferences for disclosure policies are crucial for ethical NBS programs.

Purpose of the Study:

  • To develop and test parental policy guidance for disclosing incidental NBS findings.
  • To assess parental preferences for different disclosure policies regarding CF, CRMS/CFSPID, and carrier status.

Main Methods:

  • An anonymous, internet-based survey was administered to parents of infants up to 6 months old.
  • Parents viewed animated videos presenting two scenarios involving incidental findings.
  • Respondents ranked three disclosure policies: Fully Informed, Parents Decide, and Withholding Information.

Main Results:

  • A majority of parents favored 'Parents Decide' (57%) or 'Fully Informed' (41%) for CRMS/CFSPID disclosure.
  • For CF carrier status, 'Fully Informed' (50%) and 'Parents Decide' (43%) were top choices.
  • Parents prioritized knowledge and autonomy, even with potential distress, but preferred deferring decisions if information overload was a concern.

Conclusions:

  • Most parents strongly prefer active disclosure policies over withholding information for NBS results.
  • Findings support informing NBS policies, particularly with increasing incidental findings from next-generation sequencing.
  • Parental autonomy and informed consent are key considerations in genetic screening disclosure.

Genomic Imprinting and Inheritance

Diploid organisms inherit genetic material through chromosomes from both parents. Copies of the same gene are known as alleles. In most cases, both alleles are simultaneously expressed and allow various cellular processes to function optimally. If one of the alleles is missing or mutated, the expression of the other allele can compensate; however, this is not true for all genes.
The expression of some genes depends on which parent passed the gene to the offspring, through a phenomenon known as...

Behavioral Genetics and Its Designs

Behavior genetics explores how genetic inheritance influences human behavior. It focuses on how genes, passed from parents to offspring, contribute to the development of behavioral traits and tendencies. This branch of genetics seeks to understand the complex interplay between inherited genetic factors and environmental influences in shaping our behaviors.
The primary methodologies used in behavior genetics include family studies, twin studies, and adoption studies, each providing unique...

Genetic Material

Within the human body, a complex and detailed system of trillions of cells works in unison to sustain life. Each cell houses a nucleus, which contains 46 chromosomes divided into 23 pairs. Chromosomes are highly coiled structures made of the genetic material DNA. These chromosomes are essential carriers of genetic information, with half inherited from the mother through her egg and the other half from the father's sperm, combining to create the unique genetic makeup of an individual.

Human Genetics

Human genetics provides a profound framework for understanding the interplay between genetic predispositions and human psychology. At the heart of this discipline lies the study of how genes influence physical traits, behaviors, and susceptibility to diseases. Each person carries a unique genetic code that subtly or significantly shapes their psychological and behavioral landscape.
The complex relationship between genetics and psychology is observable through common biological components such...
