Abstract
The gene coding for the α5 chain of type IV collagen (α5(IV) collagen), which maps to Xq22, is a candidate gene for the X-linked dominant disease Alport syndrome (AS). Using three cDNA clones, covering the 3′ end of the α5(IV) collagen gene, 3 of 38 patients have been identified with mutations in this gene. Each of these patients shows a gross rearrangement of DNA: a deletion of at least 35 kb, an insertion/deletion event involving approximately 25 kb, and a duplication of at least 35 kb of DNA.

Funding
The authors thank Dr. John Hoyer for his help in obtaining partial cDNA probes for &IV) collagen, the renal physicians at Guy’s Hospital for patient access, the Alport patients themselves for giving the blood samples, Dr. Ellen Solomon for critical reading of the manuscript, and Lynette Noble for secretarial assistance. This work was supported by the National Kidney Research Fund, the Medical Research Council, The Generation Trust, and the Spastics Society. Isolation of nS(IV) collagen cDNA clones was supported by NIH Grant AM20553 (to J.C.M.), and the HE6 clone was isolated by Attia Kadri. D. V. is a U.K. Commonwealth Scholar.
