Summary
Genetic factors influencing pregnancy complications like preeclampsia and gestational diabetes show conflicting results. Further research is needed to identify genetic markers for early detection and treatment of high-risk pregnancies.
Area of Science:
- Genetics
- Obstetrics
- Reproductive Medicine
Background:
- Pregnancy complications pose risks to maternal and fetal health.
- Identifying underlying causes is crucial for effective management.
- Genetic factors are increasingly recognized as potential contributors.
Purpose of the Study:
- To systematically review the genetic background of various pregnancy complications.
- To synthesize current evidence on the role of genetic polymorphisms in high-risk pregnancies.
- To assess the potential for genetic markers in early diagnosis and treatment.
Main Methods:
- Systematic literature review of studies published up to October 2018.
- Inclusion of studies on genetic factors in high blood pressure, gestational diabetes, preeclampsia, pregnancy loss, placental abruption, premature labor, and intrauterine growth retardation.
- Analysis of 164 identified articles meeting inclusion criteria.
Main Results:
- Current research on genetic polymorphisms in pregnancy complications yields contradictory findings.
- The pathogenicity of many studied genetic variations remains unclear.
- Most studies involve small sample sizes, limiting definitive conclusions.
Conclusions:
- The genetic basis of pregnancy complications requires further investigation.
- Ongoing research aims to clarify the role of genetic polymorphisms.
- Identifying reliable genetic markers could enhance diagnostic and therapeutic strategies for high-risk pregnancies.

01:07Teratogenicity
3.8K
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...

01:05Single Nucleotide Polymorphisms-SNPs
17.7K
A single nucleotide polymorphism or SNP is a single nucleotide variation at a specific genomic position in a large population. It is the most prevalent type of sequence variation found in the human genome. Point mutations that occur in more than 1% of the population qualify as SNPs. These are present once every 1000 nucleotides on an average in the human genome. Replacement of a purine with another purine (A/G) or a pyrimidine with another pyrimidine (C/T) is known as a transition. In contrast,...

02:26Comparing Copy Number Variations and SNPs
18.4K
Sequencing of the human genome has opened up several best-kept secrets of the genome. Scientists have identified thousands of genome variations that exist within a population. These variations can be a single nucleotide or a larger chromosomal variation.
Copy number variations or CNVs are the structural variations that cover more than 1kb of DNA sequence. The single nucleotide polymorphism (SNP), on the other hand, is a single nucleotide change or a point mutation that is found in more than 1%...

1.3K
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.

01:11Genome-wide Association Studies-GWAS
15.1K
Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.
GWAS does not require the identification of the target gene involved in...

02:30Genomic Imprinting and Inheritance
36.5K
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.
