Exploring the genes that influence neurological development, thyroid function, respiratory health, protein regulation, immune cell formation and the body’s ability to maintain biological balance. Introduction What connects the development of the brain, the functioning of the lungs, the regulation of thyroid hormones, the production of antibodies and the body’s ability to protect itself against abnormal cellular growth? An important part of the answer lies in Chromosome 14. Chromosome 14 contains a fascinating collection of genes involved in several essential biological processes. Some contribute to brain development and neurological function, while others regulate thyroid activity, protect lung tissue, process proteins and help the immune system recognise potential threats. Among its best-known…
