Alport's syndrome, a renal disorder with inherited transmission, is characterized by ultrastructural changes of glomerular basement membrane and basement membranes elsewhere. A progressive haematuric nephritis, sensorineural hearing loss and familial occurrence in successive generations are typical of this disorder. X-linked dominant inheritance is quite frequent (8590% of the families) [1].
Alport-like syndromes identify a group of diseases characterized by thrombocytopaenia with giant platelets and autosomal dominant transmission. Their distinguishing features consist of the presence of nephritis, cataracts, hearing loss or deafness with or without leucocytic intracytoplasmatic inclusions (named Dhole bodies). This group of diseases includes: the MayHegglin anomaly, Fechtner syndrome, Sebastian syndrome and Epstein syndrome. Unlike in Alport's syndrome, the genetic mutations linked to this group of disorders are in the human non-muscle myosin IIA
