How to Interpret WES Test Results? Meaning of Variant and Mutation
In medicine, genetic tests are an important tool for understanding individuals' genetic makeup and detecting potential health issues in advance. Particularly, the WES (Whole Exome Sequencing) test plays a critical role in diagnosing rare diseases. In this article, we will examine in detail how WES test results are interpreted, what genetic changes (variants) are, and what their meanings are.
What Are WES Test Results?
WES test results contain data obtained by examining a specific part of an individual's genetic makeup. This test allows for the sequencing of the entire exome to help understand the causes of genetic diseases. WES test results are generally divided into three main categories: pathogenic (disease-causing), benign (non-harmful), and uncertain (not yet clearly defined) variants.
- Pathogenic Variants: These types of genetic changes contribute to the development of a specific disease. For example, pathogenic variants in certain genes can lead to neurological or metabolic disorders.
- Benign Variants: These variants are changes that, despite being present in individuals' genetic makeup, do not have a negative effect on health. It is important to consider these variants in the process of understanding genetic test results.
- Uncertain Variants: The relationship of these variants to disease has not yet been clearly established. As research continues, the meaning of these variants may become clearer.
- Harmful Variants: These are genetic changes that can lead to diseases.
- Non-Harmful Variants: These are genetic changes that do not have negative effects on health.
- Uncertain Variants: Additionally, the effects of some variants are uncertain, and research is ongoing.
- Family History: If there are similar health issues in the family, this can be an important factor in interpreting the results.
- Clinical Symptoms: The individual's current health status and complaints may affect the meaning of the genetic test results.
- Research and Databases: The relationship of variants to previous research is important. Scientific databases can be used to understand the effects of specific variants on health.
What Is a Variant?
A variant refers to changes that occur in the genetic structure. These changes arise from the alteration of one or more nucleotides in the DNA sequence. Variants show diversity among individuals, and this diversity can affect many areas, from physical characteristics to health conditions.
Variants are generally studied in three main types:
What Is a Mutation?
Mutations, known as genetic changes, are alterations in the DNA sequence of a specific gene. Although the terms genetic change and mutation are often used interchangeably, mutation more specifically refers to permanent changes in the genetic structure. Mutations can occur naturally or can be caused by environmental factors.
When examining WES test results, the significance of mutations should also be considered. Mutations may play a role in the development of certain diseases and therefore hold an important place in the genetic counseling process.
Interpretation of WES Test Results
The interpretation of WES test results is an important part of the genetic counseling process. The meaning of the variants present in the results should be evaluated in conjunction with the individual's health status and family history. At this stage, genetic specialists assist families in creating the most suitable health plan for themselves.
The main factors to consider in the interpretation of results are as follows:
