How can gene variants affect health and development? - Medlin…

(6 days ago) People also askDoes genetic variation affect health and development?More than 10 percent of the human genome appears to contain differences in gene copy number. While much of this variation does not affect health or development, some differences influence a person’s risk of disease, particularly some types of cancer, or response to certain drugs.Can a change in the number of genes affect health and development medlineplus.govHow do genetic variants affect disease risk?Genetic variants identified in GWAS can increase disease risk through multiple means, including changing the amino acid of a protein, altering gene regulatory mechanisms, impacting RNA splicing, and affecting translation rates.Gene–environment interactions and their impact on human healthnature.comCan a gene variant affect a person's health?Although many of these common variations in the DNA have no negative effects on a person’s health, some may influence the risk of developing certain disorders. A gene variant (or mutation) changes the DNA sequence of a gene in a way that makes it different from most people's. The change can be inherited or acquired.What is a gene variant and how do variants occur? - MedlinePlusmedlineplus.govWhy is genetic variation important?A central reason for studying the origins and nature of human genetic variation is that the similarities and differences in the type and frequencies of genetic variations within and among populations can have a profound impact on studies that attempt to understand the influence of genes on disease risk.Genetics and Health - Genes, Behavior, and the Social Environment ncbi.nlm.nih.govFeedbackNational Center for Biotechnology Informationhttps://www.ncbi.nlm.nih.gov/books/NBK19932Genetics and HealthWeb3.
