IgA nephropathy is the most common primary glomerulonephritis worldwide. Familial clustering and genetic studies indicate significant heritability.
How Genetic Is IgA Nephropathy?
Genetics plays a meaningful role in IgA Nephropathy, with heritability estimated at around 50%. However, environmental factors — including diet, lifestyle, and exposure — also significantly influence risk.
Key genes associated with IgA Nephropathy: HLA,IGHG1,GALNT12. Variants in these genes have been identified through genome-wide association studies (GWAS) and clinical research as influencing susceptibility or severity.
