WebJun 3, 2024 · A genetic region has been discovered to be associated with clinical TB. People with at least one high-risk copy of this genetic region are ten times more likely to develop TB than normal. The genetic region contains a gene, NRAMP1, that is known to be involved in the susceptibility to leprosy , which is caused by a bacterium related to TB. WebHost genetic factors such as MBL2 gene polymorphisms can determine differences in the susceptibility or resistance to TB. 45 Recently, more studies have been conducted to identify whether the polymorphisms of exon 1 of MBL2 is the genetic determiner of TB. However, these studies yielded different or even controversial results.
WebGenetics is the study of how genes and how traits are passed down from one generation to the next. Our genes carry information that affects our health, our appearance, and even our personality! Genetics Stuff: ALL … Early case and twin studies have indicated that genetic component are important in host susceptibility to M. Tuberculosis. Recent Genome-wide association studies (GWAS) have identified three genetic risk loci, including at positions 3q23, 11p13 and 18q11. As is common in GWAS, the variants discovered have moderate effect sizes - but have shown that TB has high polygenic heritability. These studies suggest that while only a handful of alleles have been found, larger we…
