Genomic Imprinting and Inheritance02:30

Genomic Imprinting and Inheritance

36.8K
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...

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...

Incomplete Dominance01:43

Incomplete Dominance

29.6K
Gregor Mendel's work (1822 - 1884) was primarily focused on pea plants. Through his initial experiments, he determined that every gene in a diploid cell has two variants called alleles inherited from each parent. He suggested that amongst these two alleles, one allele is dominant in character and the other recessive. The combination of alleles determines the phenotype of a gene in an organism.

Genetic Screens

5.6K
Genetic screens are tools used to identify genes and mutations responsible for phenotypes of interest. Genetic screens help identify individuals or a group of people at risk of developing  genetic diseases and help them with early intervention, targeted therapy, and reproductive options.
Forward genetic screens
Forward or “classical” genetic screens involve creating random mutations in an organism’s DNA using radiation, mutagens, or insertion of additional bases, which...

Animal Mitochondrial Genetics02:59

Animal Mitochondrial Genetics

9.0K
Among all the organelles in an animal cell, only mitochondria have their own independent genomes. Animal mitochondrial DNA is a double-stranded, closed-circular molecule with around 20,000 base pairs. Mitochondrial DNA is unique in that one of its two strands, the heavy, or H, -strand is guanine rich, whereas the complementary strand is cytosine rich and called the light, or L, -strand. Compared to nuclear DNA, mitochondrial DNA has a very low percentage of non-coding regions and is marked by...

Summary
This summary is machine-generated.

Genetic research has identified over 1000 myopia variants, but heritability remains partly unexplained. Future research should integrate diverse data for personalized myopia risk prediction and prevention strategies.

Area of Science:

  • Ophthalmology
  • Genetics
  • Genomics

Background:

  • Myopia genetics research has significantly advanced since prior International Myopia Institute reports.
  • Understanding the genetic basis of myopia is crucial for developing effective interventions.

Purpose of the Study:

  • Provide an updated overview of current findings in myopia genetics.
  • Identify research priorities for the future of myopia genetics.

Main Methods:

  • Comprehensive literature review of genome-wide association studies (GWASs), rare variant analyses, functional genomics, and multiomics.
  • Focused on common and high myopia, monogenic syndromes, and gene-environment interactions.

Main Results:

  • Over 1000 common variants linked to myopia and refractive error, implicating retinal signaling, extracellular matrix remodeling, and neurodevelopmental pathways.
  • Rare variants found in new candidate genes for high and syndromic myopia.
  • Polygenic risk scores, combined with environmental factors, improve myopia prediction; gene-environment interactions are increasingly recognized.

Conclusions:

  • A significant portion of myopia heritability is still unexplained.
  • Integrative approaches combining genetic, functional, and multiomics data across diverse populations are essential.
  • Future efforts should focus on personalized risk prediction, understanding gene-environment interplay, and identifying individuals for targeted prevention/treatment.
