HGNC (Hugo) MYH9
LocusID (NCBI) 4627
Location 22q12.3
Location_base_pair Starts at 36677323 and ends at 36784063 bp from pter ( according to hg19-Feb_2009)  [Mapping]

DNA/RNA

Description spans 107 kb; 40 exons
Transcription alternate splicing; transcripts of 4.4, 5.3 and 5.9 kb

Protein

Description 1960 amino acids; 227 kDa (and 1752 aa, 202 kDa, and 1486 aa, 172 kDa; globular head in N-term and a coiled-coil tail in C-term; actin binding site and light chains binding site are present in the globular domain. Myosin forms hexamers with 2 heavy chains, 2 essential (alkali) light chains, and 2 regulatory light chains
Expression in platelets; upregulated during granulocyte differentiation (see below); also expressed in thymus, spleen, kidney, intestine, cochlea ....
Function binds actin; protein of the cytoskeleton; role in cell shape and motility, and in cell division

Mutations

Germinal in autosomal dominant giant-platelet disorders
Somatic in non Hodgkin lymphomas

Implicated in

Disease The autosomal dominant giant-platelet disorders, May-Hegglin anomaly (MHA), Fechtner syndrome (FTNS), and Sebastian syndrome (SBS), which share a triad of thrombocytopenia, large platelets (macrothrombocytopenia (MTCP)) and characteristic leukocyte inclusions (Dohle-like bodies), Epstein syndrome, which associates additional Alport-like clinical features (inherited sensorineural deafness, cataracts, nephritis), and MTCP without leukocyte inclusions, as well as a nonsyndromic hereditary hearing impairment are all caused by (germinal) mutations in MYH9. These disorders appear to represent a class of allelic disorders with variable phenotypic diversity. No clear no genotype-phenotype correlation was identified
  
Entity Anaplasic large cell lymphoma (ALCL) with t(2;22)(p23;q12) --> ALK- CLTC
Disease ALCL are high grade non Hodgkin lymphomas; ALK+ ALCL are ALCL where ALK is involved in a fusion gene; ALK+ ALCL represent 50 to 60 % of ALCL cases (they are CD30+, ALK+;); belong to the "cytoplasmic ALK+" subset.
Prognosis Althouth presenting as a high grade tumour, a 80% five yr survival is associated with this anomaly
Hybrid/Mutated Gene 5' MYH9 - 3' ALK
Abnormal Protein NH2 MYH9 - COOH ALK
