What is the rs9282858 variant?
rs9282858 is a SNP (single nucleotide polymorphism) in the SRD5A2 (Steroid 5 Alpha-Reductase 2) gene. It belongs to the Metabolic category and is part of the Metabolic Regulation biological cluster. SRD5A2 encodes 5α-reductase type 2, which converts testosterone to the potent androgen DHT in the prostate and other tissues.
Biological role and pathway
This variant sits within the SRD5A2 gene, which is involved in the DHT biosynthesis pathway. Genes within the Metabolic Regulation cluster work together to maintain balanced function across interconnected biological systems.
Variants in genes within this pathway may influence an individual's predisposition to altered function — particularly under conditions of physiological stress such as viral infection or prolonged illness.
rs9282858 and Long COVID / ME-CFS research
SRD5A2-mediated DHT production activates the androgen receptor driving TMPRSS2 expression; variants may affect androgen-mediated TMPRSS2 upregulation and SARS-CoV-2 entry susceptibility in Long COVID.

Frequently asked questions
What is the rs9282858 variant in the SRD5A2 gene?
rs9282858 is a single nucleotide polymorphism (SNP) located in the SRD5A2 (Steroid 5 Alpha-Reductase 2) gene, which is involved in DHT biosynthesis. SRD5A2 encodes 5α-reductase type 2, which converts testosterone to the potent androgen DHT in the prostate and other tissues.
How may the rs9282858 variant relate to Long COVID or ME/CFS?
SRD5A2-mediated DHT production activates the androgen receptor driving TMPRSS2 expression; variants may affect androgen-mediated TMPRSS2 upregulation and SARS-CoV-2 entry susceptibility in Long COVID.
Can a consumer DNA test detect the rs9282858 variant?
Many consumer DNA tests such as 23andMe, AncestryDNA, and MyHeritage genotype common SNPs. ChronicDNA analyses your raw DNA file and reports on variants studied in relation to chronic illness, immune function, and metabolism. This is not a diagnostic service — results are informational and educational only.
