VDR Gene Single Nucleotide Polymorphisms and Autoimmunity: A Narrative Review.

Area of Science:

• Immunology
• Genetics
• Endocrinology

Background:

• The vitamin D/Vitamin D receptor (VDR) axis is vital for numerous physiological processes, including immune function.
• Autoimmune diseases result from genetic predisposition and environmental triggers, with Vitamin D's role frequently implicated.
• Specific variations in the VDR gene, known as single nucleotide polymorphisms (SNPs), have been linked to autoimmune disorders.

Purpose of the Study:

• To review the scientific literature on the role of Vitamin D/VDR in autoimmunity.
• To summarize evidence linking specific VDR gene SNPs (ApaI, BsmI, TaqI, FokI) to the pathogenesis of autoimmune diseases.
• To explore the potential of understanding these molecular mechanisms for novel therapeutic strategies.

Main Methods:

• Literature review of scientific studies.
• Analysis of evidence connecting VDR SNPs to autoimmune conditions.
• Synthesis of data on the molecular mechanisms involved.

Main Results:

• The vitamin D/VDR complex regulates genes involved in both innate and adaptive immunity.
• Certain VDR SNP alleles and genotypes are associated with a modified risk of developing various autoimmune diseases.
• These genetic variations can either increase or decrease the likelihood of disease onset.

Conclusions:

• The VDR gene's SNPs are implicated in the susceptibility and development of autoimmune conditions.
• Understanding the interplay between Vitamin D/VDR signaling and autoimmunity is crucial.
• This knowledge may pave the way for developing new therapeutic approaches for autoimmune disorders.
