Renal Macrocystic Disease v0.72 COL4A3 Bryony Thompson changed review comment from: PMID: 38514012 - Multiple kidney cysts, usually with normal kidney volume, were found in 37% (26/70) of patients with a genetically confirmed AS (COL4A3-5). A few patients' kidney volumes were similar to autosomal dominant polycystic kidney disease. The prevalence of cystic kidney phenotype was significantly higher in patients with AS compared to those with IgA nephropathy (42% vs 19%; P=0.002).

PMID: 39190485 - Enrichment of monoallelic COL4A3 rare variants (P = 1.26e-6, OR 3.02, 95% CI 2.10-4.22) in 100K GP cystic kidney disease cohort. Enrichment in “unsolved” (eg removing PKD1 & PKD2 diagnoses), n=308 (P = 6.83e-7, OR 4.93, 95% CI 2.77-8.11).
15/1209 - 9 are Gly-altering in the collagen triple helix domain, 1 stopgain, & 5 missense/inframe indel. 4 of the COL4A3 cases had liver cysts
100K GP WGS case-control analysis: cystic kidney disease cohort n=1209 vs ancestry-matched controls n=29,096. Gene-based collapsing rare variant association with SAIGE-GENE (P<2.6e-6).
Sources: Literature; to: PMID: 38514012 - Multiple kidney cysts, usually with normal kidney volume, were found in 37% (26/70) of patients with a genetically confirmed AS (COL4A3-5), mostly ADAS. A few patients' kidney volumes were similar to autosomal dominant polycystic kidney disease. The prevalence of cystic kidney phenotype was significantly higher in patients with AS compared to those with IgA nephropathy (42% vs 19%; P=0.002). The cystic phenotype in the AS patients was associated with an older age and lower eGFR levels.
