A genetic profile is a unique and detailed representation of an individual's DNA, comparable to a molecular fingerprint.
It is a highly sophisticated form of "genetic ID card" that allows for the identification of a person with remarkable precision, achieving exceptional reliability rates.
This profile is meticulously established by analyzing specific regions of DNA, called genetic markers, which show natural variations from person to person.
These variations, inherited from our parents, constitute a unique biological signature that distinguishes each individual, with the exception of monozygotic twins.
What is a genetic profile?
Obtaining a genetic profile is a process that requires several technical steps performed under strictly controlled conditions:
​
-
Collection of a biological sample under sterile conditions and according to standardized protocols to ensure sample quality
-
DNA extraction from the biological sample using specialized techniques that isolate and purify the genetic material
-
Amplification of regions of interest through PCR (Polymerase Chain Reaction), a technique that reproduces specific DNA segments millions of times for study
-
Analysis of genetic markers using sophisticated equipment that can precisely detect and measure variations in DNA sequences
-
Interpretation of results by qualified experts who examine the obtained data and establish the final genetic profile following rigorous quality assurance protocols
How to obtain a genetic profile?
Reading a genetic profile requires a thorough understanding of its structure and particular organization.
This reading, although technical, follows a precise logic that allows for correct interpretation of genetic information:
​
-
Each locus is identified by a specific name, typically an internationally standardized combination of letters and numbers, allowing for clear and unambiguous identification of the analyzed DNA region
-
For each locus, two numbers are indicated, representing the alleles inherited from the father and mother respectively. These numerical values form the basis of individual genetic identification
-
These numbers correspond to the size of measured DNA fragments, expressed in the number of repetitions of the base sequence. This precise measurement allows for accurate characterization of present genetic variations
-
The presence of a single number indicates that both alleles are identical (homozygous), meaning the individual inherited the same version of the genetic marker from both parents
Reading a genetic profile
A genetic profile consists of several key elements:
​
-
Locus: This is a precise location on a chromosome where a specific DNA sequence is found. Each locus studied in a genetic profile is chosen for its high variability between individuals.
-
Alleles: These are different versions of the same gene that can exist at a given locus. Each person has two alleles for each locus, one inherited from each parent.
-
Genetic markers: These are specific DNA sequences used for identification. Modern genetic profiles typically analyze between 15 and 23 different markers.
Laboratories perform a thorough analysis of several specific DNA regions to establish a complete and accurate genetic profile:
​
-
STR (Short Tandem Repeats) sequences - these particular DNA segments are short, repetitive sequences that show remarkable variability between individuals, making them ideal markers for genetic identification
-
The analysis covers a substantial set of 15 to 21 different loci, carefully selected and studied to ensure optimal reliability of results and minimize the risk of error
The rigorous and methodical selection of these DNA regions is based on a set of scientific criteria carefully established and validated by the international scientific community:
​
-
Their strategic and precise positioning within non-coding DNA regions, which constitute about 98% of our total genome, allows for thorough analysis without risk of interference with essential functional genes, thus ensuring the safety and relevance of genetic analysis
-
These specific regions are distinguished by their remarkable variations (polymorphisms) that are particularly expressed in the frequency and pattern of nucleotide sequence repetition. This unique characteristic gives these markers exceptional discriminating power, allowing for precise and reliable identification of individuals
To illustrate this concept, let's take the example of a specific sequence like AAGTA: this particular combination of nucleotides can repeat in variable patterns unique to each individual (for example, 11 repetitions in one person, while others might have 14 or 15 repetitions of the same sequence)
Composition of a genetic profile
​
Genetic profiles can be established from different types of samples:
​
Saliva samples
​
Saliva samples are most commonly used because:
-
Easy to collect
-
Non-invasive
-
Stable at room temperature
-
Excellent success rate for DNA extraction
Non-saliva samples
Other types of samples can be used:
-
Blood
-
Hair (with bulb)
-
Buccal cells
-
Biological tissues
Types of usable samples

Who can take a DNA test for genetic profiling?
Access to DNA testing for genetic profiling is regulated differently depending on the country and context:
Medical context
-
Patients requiring genetic diagnosis with medical prescription
-
Pregnant women as part of prenatal diagnosis
-
People participating in approved medical research studies
Legal context
-
People involved in legal proceedings (court-ordered paternity tests)
-
Justice professionals in criminal investigations
-
Individuals wishing to officially establish family relationships
It's important to note that regulations regarding DNA testing vary considerably between countries. In some countries, over-the-counter genealogical or health DNA tests are allowed, while in others, they are strictly regulated or prohibited without medical or legal supervision.
​
Before undertaking a DNA test, it is advisable to:
​
-
Check the legislation in your country
-
Consult a healthcare professional or genetic counselor
-
Ensure the reliability and accreditation of the testing laboratory
-
Understand the ethical implications and potential consequences of the results
Who can take a DNA test for genetic profiling?
Genetic profiling has numerous applications:
Medical applications
-
Diagnosis of genetic diseases
-
Personalized medicine
-
Prenatal screening
Legal and forensic applications
-
Personal identification
-
Paternity testing
-
Criminal investigations
Genealogical research
-
Study of family origins
-
