Preterm baby delivery: Some genetic epidemiological aspects
1Research Unit-Human Population Biology, Department of Anatomy and Anthropology, Sackler Faculty of Medicine, Tel Aviv University, Ramat Aviv 69978, Tel Aviv, Israel.
Summary
Genetic factors contribute to preterm birth risk, with family resemblance playing a role. While some markers show correlation, more data is needed to precisely determine genetic and environmental influences on premature delivery.
Area of Science:
- Genetics
- Obstetrics
- Reproductive Medicine
Background:
- Preterm birth is a significant global health concern with complex etiology.
- Understanding genetic and environmental risk factors is crucial for prevention and intervention.
Purpose of the Study:
- To investigate the genetic and family resemblance components predisposing mothers to preterm birth.
- To explore the predictability of preterm delivery risk using morphometric traits and biochemical genetic markers in early pregnancy.
Main Methods:
- Analysis of family resemblance in gestational age.
- Discussion of path analysis models for estimating genetic and environmental contributions.
- Correlation analysis of biochemical markers and morphological asymmetry with preterm delivery predisposition.
Main Results:
- Evidence suggests a significant family component in preterm birth risk.
- Certain biochemical markers and morphological asymmetry show correlations with preterm delivery predisposition.
- Distinguishing between fetal genotype, maternal environment, and maternal genotype contributions remains challenging.
Conclusions:
- A genetic or family component is implicated in preterm birth.
- Morphometric traits and biochemical markers may serve as predictive indicators, but require further validation.
- More empirical data are essential for a comprehensive understanding of preterm birth etiology and accurate risk prediction.

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...

01:07Teratogenicity
4.4K
The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...

1.2K
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.

02:27Background and Environment Affect Phenotype

Although the genetic makeup of an organism plays a major role in determining the phenotype, there are also several environmental factors, such as temperature, oxygen availability, presence of mutagens, that can alter an organism’s phenotype.
An example of how genetic background affects phenotype can be seen in horses. The Extension gene in horses is responsible for their coat color. A wild-type gene (EE) produces black pigment in the coat, while a mutant gene (ee) produces red pigment. A...

Genome editing technologies allow scientists to modify an organism’s DNA via the addition, removal, or rearrangement of genetic material at specific genomic locations. These types of techniques could potentially be used to cure genetic disorders such as hemophilia and sickle cell anemia. One popular and widely used DNA-editing research tool that could lead to safe and effective cures for genetic disorders is the CRISPR-Cas9 system. CRISPR-Cas9 stands for Clustered Regularly Interspaced...

Diabetes mellitus is a chronic metabolic disorder characterized by hyperglycemia. The four categories of diabetes are type 1 diabetes, type 2 diabetes, other specific types of diabetes, and gestational diabetes.
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility,...
