Just under half – 49% – of Americans get their health insurance through their employer, according to the Henry J. Kaiser Family Foundation. Another 19% of Americans are insured under Medicaid, 14% under Medicare, seven% under non-group plans and two% under other public insurers, while nine% of U.S. citizens remain uninsured.

The TWIST1 gene, located on chromosome 7p21.1, is essential for embryonic development and plays a critical role in regulating cell migration, proliferation, and differentiation. Mutations in this gene have been associated with several health conditions and syndromes, including:

• Saethre-Chotzen syndrome: Saethre-Chotzen syndrome is a genetic disorder characterized by craniosynostosis, where the bones in the skull fuse prematurely. Mutations in the TWIST1 gene are responsible for a significant proportion of Saethre-Chotzen syndrome cases.
• Drosophila tangle syndrome: Drosophila tangle syndrome is a neurodegenerative disorder found in fruit flies. Studies in Drosophila have shown that the TWIST1 gene is necessary for the normal development of neural tissues.

Testing for genetic changes

Identifying genetic changes associated with health conditions often involves genetic testing. Several resources, such as PubMed, OMIM, and scientific databases, provide information on genetic changes, genes, and associated health conditions.
