GEDNAP Proficiency Tests 70 & 71 (2025)

https://upload.ifmg-ms.de/register/

If you participated in GEDNAP 68 and/or GEDNAP 69, remember to click the “existing participant” button. You’ll then be prompted to enter an invoice number from last year’s test to complete your registration.

What’s New for GEDNAP 70 & 71?
We’ve made some significant enhancements to this year’s tests:
• Expanded STR Modules: Modules 1, 2, 5, and 6 now include an interpretation component, specifically addressing “Who has contributed to stain 1, 2, 3, and 4?”
• New Biogeographic Analysis Module: We’ve added Module 14, focusing on the biogeographic analysis of three reference samples.
• Quantitative Parentage Testing Evaluation: Module 13 (Parentage Testing) will now be evaluated quantitatively, providing a clear pass/fail result based on both STR typing and biostatistical analysis.

These updates aim to further enhance the comprehensiveness and utility of the GEDNAP proficiency tests.

GEDNAP workshop 2025

The 2nd GEDNAP Workshop took place on 21 February 2025.
Attendees met in-person in the Hotel Moevenpick, Muenster (Germany) and remote attendees dialled in virtually. In addition to the presentation of the evaluation of the GEDNAP proficiency tests 68 & 69 there were presentations focussing on forensic DNA extraction and on the boosting field of forensic investigative genetic genealogy (FIGG).
The program is available online at the following URL:

Module 7 (biostatistical calculation) GEDNAP 68 & 68 available

The paper challenge files of the GEDNAP Proficiency Tests 68 & 69 (module 7, biostatistical calculations) haven been sent out today to the participants by email.
Both calculation methods that are recommended by P. Schneider et al. (2009) Int J Legal Med 123:1–5), i.e., LR and RMNE, are expected. Only the allele frequencies that were observed in the course of an ENFSI population study (source: “Europe” in STRidER_frequencies_2019-08-02, https://STRider.online) sh all be used. They can be downloaded from the GEDNAP website (https://www.gednap.org/wp-content/uploads/2020/09/STRidER_R2.zip). For rare alleles the recommendations (W. Ulbrich et al. (2016) Rechtsmedizin 26: 291-298) shall be followed. The frequency of rare alleles (fmin) shall be estimated according to the NRC report (1996). If the estimated fmin is below 0.001, one shall use the value 0.001. The calculation steps must be documented by a print-out. The employed software version must be named. Please note that the calculations have to be executed without the correction factor ‘theta’ (i.e. with a theta value of zero).
The deadline for result submission will be 06 December 2024.
The evaluation of the results will be provided to the participants in February 2025.

update: STR allele frequencies Europe

A new release of STRidER (STRs for Identity ENFSI Reference Database), the expanded and enhanced version of the ENFSI STRbASE (2004-2016), is available here since March 30, 2020: https://STRidER.online).
In Germany it is recommended to use most recent the European allele frequencies as a standard. To receive periodic news and stay updated about STRidER, you may register here for the STRidER newsletter:

For the biostatistics modules of the GEDNAP proficiency tests in 2020 the recent allele frequencies [source: "Europe" in STRidER_frequencies_2019-08-02] will be used as well.

GEDNAP Proficiency Tests 68 & 69 result submission

Due to numerous late registrations and the new parentage testing module the result submission mode has not been activated so far. In the next week (i.e., week 45), entering results will be made possible. Participants will be informed immediately after activation.
