Macrothrombocytopenia And Granulocyte Inclusions With Or Without Nephritis Or Sensorineural Hearing Loss; Matins

Description

Macrothrombocytopenia with or without granulocyte inclusions, nephritis, or sensorineural hearing loss was previously thought to be comprised of 4 distinct entities with overlapping features: Fechtner syndrome, May-Hegglin anomaly, Epstein syndrome, and Sebastian syndrome. Fechtner syndrome was characterized by the triad of thrombocytopenia, giant platelets, and Dohle body-like inclusions in peripheral blood leukocytes, with the additional Alport syndrome (OMIM )-like features of nephritis, hearing loss, and eye abnormalities, predominantly cataracts (Peterson et al., 1985). May-Hegglin anomaly was characterized by the triad of thrombocytopenia, giant platelets, and Dohle body-like inclusions in peripheral blood leukocytes. Epstein syndrome was characterized by thrombocytopenia, deafness, and nephritis, and lacked leukocyte inclusion bodies on classic staining of peripheral blood smears. Sebastian syndrome was similar to May-Hegglin anomaly, but had a different ultrastructural appearance of the leukocyte inclusions. Seri et al. (2003) suggested that these 4 disorders were not distinct entities, but rather represented a single disorder with a continuous clinical spectrum because variable phenotypic expression is observed not only between families but also within families having the same MYH9 mutation. In addition, Balduini et al. (2011) noted that all patients present leukocyte inclusion bodies, although of variable size. Seri et al. (2003) proposed the term 'MYH9-related disease' for the disorder; however, an isolated form of nonsyndromic deafness (DFNA17 ) is also caused by mutation in the MYH9 gene.
