Abstract
Background: Chronological age estimation is a challenging marker in the field of forensic medicine.
The current study aimed to investigate the accuracy of signal joint T-cell receptor rearrangement excision
circles (sjTRECs) quantification and telomere length measurement as methods for estimating
chronological age.
Methods: Telomere length was estimated in the DNA derived from the buccal cells through estimating
the telomeric restriction fragment (TRF) length using TeloTTAGGG Telomere Length Assay while
the sjTRECs quantification was carried out on DNA isolated from the blood samples using qPCR.
Results: The TRF length was shortened with increased age (r ¼ 0.722, p
