[Symptomatic dermatographism and HLA antigens].
This research reports the unique case of manifestation of symptomatic dermographism which includes all of its twenty five members of the family. Probing a genetic transmission autosomal dominant manner and taking into account the highly probable role of HLA in this illness. The symptomatic dermographism correspond to a group of physical familiar urticarias with symptoms appearing in early childhood and evolving throughout adulthood with seldom periods of remission. Due to the fact that all patients were affected, it was not possible to realize a typification of HLA antigens with persons not affected, to establish a relationship with the data obtained. However, results show a significant association of haplotypes; HLA A2 (78.95), B16 (68.4%), A1 (47.3%), and B5 (42.5%) among the most important. This is the first research that reports the analysis of HLA within the physical familial urticarias.
