Fechtner syndrome, a variant of Alport syndrome, was first reported by Peterson et al. . It is characterized by nephritis, hearing loss, eye abnormalities, macrothrombocytopenia, and leucocyte inclusions, present in varying combinations in several members of the same family. This is the second family reported; 16 relatives are affected. The clinical manifestations of the syndrome are delineated. The pattern of inheritance is autosomal dominant. The hematologic abnormalities are similar to those detected in May Hegglin anomaly. They are present in every affected relative and may be present at birth. The feasibility of prenatal diagnosis is discussed.
