Importance Of Understanding Genetic Predisposition, Andrew Carter Apr 2021

Importance Of Understanding Genetic Predisposition, Andrew Carter

Thinking Matters Symposium

Hypersensitivity reactions can be sudden and are often fatal. Many of these reactions occur as a result of allergies to prescribed medication. Adverse drug reactions or (ADR’s) were show in a recent study to affect over 6% of hospitalized patients and resulted in over 100,000 deaths a year in the US alone. This poster will review the importance of understanding genetic predisposition, through articles about possible genetic causes of allergies to penicillin and other beta-lactams. Changes in a specific HLA gene located on chromosome 6 showed a correlation to penicillin reactions in over 600,000 participants. Another study found a conclusive …

The human gut microbiome consists of at least 3 million non-redundant genes, 150 times that of the core human genome. Herein, we report the identification and characterisation of a novel stress tolerance gene from the human gut metagenome. The locus, assigned brpA, encodes a membrane protein with homology to a brp/blh-family β-carotene monooxygenase. Cloning and heterologous expression of brpA in Escherichia coli confers a significant salt tolerance phenotype. Furthermore, when cultured in the presence of exogenous β-carotene, cell pellets adopt a red/orange pigmentation indicating the incorporation of carotenoids in the cell membrane.
