MYH9-related platelet disorders.
Myosin heavy chain 9 (MYH9)-related platelet disorders belong to the group of inherited thrombocytopenias. The MYH9 gene encodes the nonmuscle myosin heavy chain IIA (NMMHC-IIA), a cytoskeletal contractile protein. Several mutations in the MYH9 gene lead to premature release of platelets from the bone marrow, macrothrombocytopenia, and cytoplasmic inclusion bodies within leukocytes. Four overla...
متن کاملFive (un)easy pieces: the MYH9-related giant platelet syndromes.
cytoplasmic inclusions were first noted by May almost 100 years ago.7 FTNS is distinguished by the additional clinical features of high-tone sensorineural deafness, cataracts, and nephritis. APSM is similar to FTNS except that Döhle-like inclusions have not been described and it is distinguished from the classical X-linked form of Alport syndrome in that COL4A5 gene mutations are not present. F...
متن کاملThrombin generation in two families with MYH9-related platelet disorder.
MYH9-related platelet disorders are inherited macrothrombocytopenias with additional clinical manifestations including renal failure, hearing loss, pre-senile cataract, and inclusion bodies in leucocytes that are present in different combinations. The MYH9 gene codes for the cytoplasmic contractile protein non-muscular myosin heavy chain IIA, present in several tissues. The bleeding tendency is...
متن کاملMutation spectrum and genotype-phenotype correlations in a large French cohort of MYH9-Related Disorders
MYH9-Related Disorders are a group of rare autosomal dominant platelet disorders presenting as nonsyndromic forms characterized by macrothrombocytopenia with giant platelets and leukocyte inclusion bodies or as syndromic forms combining these hematological features with deafness and/or nephropathy and/or cataracts. They are caused by mutations in the MYH9 gene encoding the nonmuscle myosin heav...
متن کاملRod mutations associated with MYH9-related disorders disrupt nonmuscle myosin-IIA assembly.
MYH9-related disorders are autosomal dominant syndromes, variably affecting platelet formation, hearing, and kidney function, and result from mutations in the human nonmuscle myosin-IIA heavy chain gene. To understand the mechanisms by which mutations in the rod region disrupt nonmuscle myosin-IIA function, we examined the in vitro behavior of 4 common mutant forms of the rod (R1165C, D1424N, E...
