NCIt definition : Human TPM3 wild-type allele is located in the vicinity of 1q21.2 and is approximately
39 kb in length. This allele, which encodes tropomyosin alpha-3 chain protein, is
involved in the mediation of muscle filament movement. Mutation of the gene is associated
with nemaline myopathy type 1 and thyroid papillary carcinoma. A chromosomal rearrangement
affecting this gene and the NTRK gene is associated with thyroid papillary carcinoma.
A chromosomal translocation t(1;2)(q25;p23) of the gene and the ALK gene is associated
with rare cases of both anaplastic large cell lymphoma and inflammatory myofibroblastic
tumors.;
