(1) Overview

Project description

The Bioresource was established in 1976 at a laboratory situated at the G. Gaslini Institute which has a longstanding tradition and internationally recognized expertise in the diagnosis of, and research into, rare genetic diseases. Therefore, interrelated laboratory activities, supported by skilled clinicians, pathologists, biochemists and molecular biologists, have allowed the establishment, over the course of years, of the Biobank which preserves well-documented biospecimens and associated data.

In fact, the Biobank was initially created as private collection to maintain rare mutant cell lines from genetic-metabolic diseases with the two essential needs to (i) have the availability of the index cases for genetic counselling and prospective prenatal diagnosis in the related families, as well as, (ii) cryopreserve precious biological material from undiagnosed patients for retrospective diagnosis. Shortly afterwards, in 1980, data from the sample collection was organised in a database and the hard-copy catalogue was promoted into the scientific community [1].

However, the Biobank made a genuine step forward, in the mid-90s, when one of the biggest biomedical Italian charity, Telethon Foundation, started to support genetic biobanks through peer review-based annual projects. Indeed thanks to these grants the Biobank has begun an efficient service of high quality standards, with the first online catalogue in 1997 and its own home page since 2001. Another substantial change and step forward has been taking place from 2008 when the Biobank, under another Telethon project, has been one of the founding partner and coordinator centre of the first Network of Genetic Biobanks (http://www.biobanknetwork.org) [2].

(2) Methods

Steps

To access to the biobanking service, users are requested to fill in the relevant pre-printed form to provide data of the patient/donor (e.g. personal, clinical, paraclinical, genetic data, etc.). The form is supplied by the Biobank staff or available online on the Biobank website. Signing the submission form, the user also accepts the policies and rules of the Biobank, that are: (i) providing donor’s clinical and laboratory documentation; (ii) sending donor’s (or legal guardian’s) appropriate written informed consent; (iii) not using the sample for commercial purposes; (iv) not using the sample for another project beyond what was approved; (v) citing the Bioresource in the acknowledgements of any resulting scientific production.

Once the sample is accepted, it undergoes codification and processing. In parallel, data of the coded samples are recorded in the Bioresource database which is protected by individual password assigned by the Director to the biobank staff. Generally, data set includes personal data (name, date of birth, address, ethnic origin), sex, phenotype (affected/not affected), essential anamnestic data, presence of consanguinity, presence of familiarity, clinical anomalies, laboratory anomalies, diagnosis, type of diagnosis and centre performing diagnosis. Traceability of the samples is kept by separate clinical and paraclinical patient’s data recordings.

Stabilization/preservation

Glycerol or DMSO (cryopreservation).

Type of long-term preservation

Frozen and Glycerol or DMSO (cryopreservation).

Storage temperature

  • From -20°C to -180°C (liquid nitrogen)
  • Storage duration: until the sample is undegraded (DNA/RNA) or viable (cell line)

Shipping temperature from patient/source to preservation or research use

Room temperature (18-25°C) and/or dry ice (-80°C) depending on the biospecimen type.

Shipping temperature from storage to research use

Room temperature (flask of cell cultures, DNA samples); dry ice (vials of frozen cell lines, RNA samples).

Quality assurance measures

The Biobank host-laboratory operates in compliance with International Standard for Quality Management System (UNI EN ISO 9000) and International Standard for Quality Management System for clinical laboratory (UNI EN ISO 15189) and Joint Commission on Accreditation of Healthcare Organization. Main measures:

  1. Procedures to guarantee that the cell lines are free of mycoplasma, bacteria, and fungi.
  2. Procedures for the sample authentication, based on genetic profile (STR).
  3. Systematic detection/exclusion of mycoplasma before distribution service.
  4. Check for DNA integrity by agarose gel electrophoresis.
  5. Controlled access to the cryocontainer room.
  6. Regular replenishment of liquid nitrogen by the assigned staff of the host “G. Gaslini” Institute.
  7. Freezers equipped with an alarm system to ensure an immediate intervention in case of an electrical blackout.
  8. CO2 incubators equipped with an alarm system to check temperature and % of CO2 variations.
  9. Both computer files and hard copies for data collecting undergo encoding procedure.
  10. Clinical revision of the patients’ data chart by clinicians experts in the field.

Source of associated data

Medical records, laboratory reports, instrumental findings, results from previous studies on those samples.

Access criteria

Basic rules to access to Biobank service are applied to all researchers, including Biobank staff, according to the following criteria:

  1. The Biobank must guarantee the storage of an adequate aliquot of sample derived from affected individuals in order to offer the possibility of retrospective analysis on the basis of more recent scientific acquisitions;
  2. Sample distribution only to qualified professionals working at research or medical institutions engaged in health-related research or health care;
  3. Appropriate justification for use (description of the research project, grant sponsor, expected results);
  4. Project employing the samples in agreement with the Biobank mission;
  5. Payment for shipping cost and a partial coverage of the cost of some basic procedures (cost recovery) related to the Biobank distribution service;
  6. Guarantee of proper acknowledgments in the resulting scientific publication.

(4) Reuse potential

The Biobank, being a member of a Network, manages all sample request through a shared IT infrastructure on the proper website upon users’ registration. All the submitted requests are gathered in a unique Request Control Panel, a tool where each Network Partner can manage their own requests after the Committee approval of the submitted project. No samples are sent before receiving the “Material Transfer Agreement” form signed by the Principal Investigator. Published and/or non-published analytical results obtained are gathered through the relevant “Confirmation of sample use” form that the Biobank periodically sends to the Users.

Up to now, the contribution of the Biobank has been expressed in acknowledgement notes in 145 scientific manuscripts.
