May 2023 in “GSC biological and pharmaceutical sciences” Forensic DNA phenotyping is becoming useful for predicting physical traits in criminal investigations but is limited by ethical concerns and incomplete genetic understanding.
May 2023 in “Zenodo (CERN European Organization for Nuclear Research)” Forensic DNA phenotyping can predict physical traits from DNA but faces challenges in knowledge and ethics.
Forensic DNA phenotyping (FDP) from low template DNA (LT-DNA) has advanced with the integration of machine learning (ML) models, improving predictive accuracy for traits like eye and hair color, with AUC > 0.9 for eye color and up to 15% improvement in SNP recovery. Tools such as HIrisPlex-S and VISAGE panels are effective for eye and hair color prediction, though challenges remain for skin tone, age, and facial morphology, especially in admixed populations. Future efforts should focus on multi-omics integration, portable sequencing, and inclusive datasets to enhance accuracy and ethical compliance in forensic applications.
