Association of certain human leukocyte antigens with nephropathic cystinosis in the absence of linkage between these loci.
The HLA phenotypes of 41 patients (22 males and 19 females) with classical nephropathic cystinosis were analyzed and compared with those reported from a control group of 1,465 Americans of Caucasian origin. There was a significantly increased association of cystinosis with HLA B7, and a reduced association with A9. The calculated A3B7 and A1B7 haplotypes were also significantly increased in cystinosis. Lod score analysis of five families indicated that linkage between the gene(s) for cystinosis and the HLA loci is unlikely. While associations of other genetic diseases with specific HLA types should be sought, such relationships, as documented here, do not imply true genetic linkage.
