HB 5149 prohibits the Texas Department of Family and Protective Services (DFPS) from collecting or using DNA samples from children in its foster care system without either the written consent of the child’s primary caregiver or a court order. The law directly affects children under DFPS conservatorship and their caregivers, requiring explicit permission or judicial approval before DNA collection. Key provisions mandate that DFPS cannot use DNA for any purpose - such as genetic databases or identification - without these safeguards. The bill takes effect September 1, 2025, and aligns with broader privacy protections for foster youth.
