Knowing every child's life is sacred, we promise to improve the well-being of every child in our care and our communities. Cook Children's Genetics investigators understand that parenting children with complex medical needs is hard. When medications don't work, or cause reactions, not only does your child continue to live with their medical condition, but you and their providers may struggle to know what the next steps should be. The Cook Children's Pharmacogenetic (PGx) research team's goal is to improve the treatment of children in all specialties through research on how genetics affect treatment. We partner with Cook Children's specialty clinics, including: psychiatry, hematology/oncology, gastroenterology (GI), and rheumatology to offer PGx opportunities. Not only are we working with these specialties to conduct research, but also to pioneer the Cook Children's Pharmacogenetics program. Providers, researchers, and patients all play a part in improving pharmacogenetic medicine. We hope that future Cook Children's patients can experience all the benefits of precision medicine through PGx testing and are so grateful to be involved in the process.
