Genetic data refers to personal data relating to the genetic, hereditary, or acquired characteristics of a natural person, resulting from the analysis of a biological sample from the individual in question, particularly the analysis of chromosomes, deoxyribonucleic acid (DNA), or ribonucleic acid (RNA), or the analysis of another element (e.g., blood and saliva) that provides equivalent information.

Genetic data, along with biometric data, health data, and identifying data regarding ethnic origin, opinions, and beliefs of a person, and trade union membership, constitute “special categories of data” (previously defined as sensitive data under the GDPR).

The GDPR prohibits the processing of special categories of data without the explicit consent of the data subject, for one or more specified purposes.
