We have generated and characterized cDNA clones providing the complete amino acid sequence of the human type IV collagen chain whose gene has been shown to be mutated in X chromosome-linked Alport syndrome. The entire translation product has 1,685 amino acid residues. There is a 26-residue signal peptide, a 1,430-residue collagenous domain starting with a 14-residue noncollagenous sequence, and a Gly-Xaa-Yaa-repeat sequence interrupted at 22 locations, and a 229-residue carboxyl-terminal noncollagenous domain. The calculated molecular weight of the mature alpha 5(IV) chain is 158,303. Analysis of genomic DNA from members of a kindred with Alport syndrome revealed a new HindIII cleavage site within the coding sequence of one of the cDNA clones characterized. The proband had a new 1.25-kilobase HindIII fragment and a lack of a 1.35-kilobase fragment, and his mildly affected female cousin had both alleles. The mutation which was located to exon 23 was sequenced from a polymerase chain reaction-amplified product, and shown to be a G----T change in the coding strand. The mutation changed the GGT codon of glycine 521 to cysteine. The same mutation was found in one allele of the female cousin. The results were confirmed by allele-specific hybridization analyses.
