NCIt definition : A fusion gene that results from a chromosomal rearrangement involving the short arms
of chromosomes 7 (7p) and 3 (3p) that fuses the first 3 exons of the ACTB gene in
frame with exon 3 of the MITF gene. This fusion is associated with a subset of clear
cell neoplasms with melanocytic differentiation characterized by MITF pathway activation.;
NCIt note : The ACTB/MITF fusion was characterized using RNAseq; the fusion protein has not been
characterized.;
