DNAJB1-PRKACA

Wednesday 6 July 2016

Fibrolamellar carcinoma has a distinctive morphology and immunophenotype, including cytokeratin 7 and CD68 co-expression.

Recently, fibrolamellar carcinomas were found to harbor a characteristic somatic gene fusion, DNAJB1 - PRKACA.

FISH for the PRKACA rearrangement is a clinically useful tool to confirm the diagnosis of fibrolamellar carcinoma, with high sensitivity and specificity.
