Alport syndrome (AS) is a predominantly X-linked hereditary nephritis associated with high-tone, sensorineural deafness and characteristic eye signs. Clinical diagnostic criteria were defined in 1988. Most cases result from mutations in the X-linked collagen gene COL4A5, with mutations in the autosomal genes COL4A3 and COL4A4 on chromosome 2 accounting for the rest. Mutation analysis of COL4A5 with a combination of sequencing and multiplex ligation-dependent probe amplification has been available for several years. The objective of this study was to determine the utility of clinical diagnostic criteria in identifying patients likely to have a COL4A5 mutation.
