Fusion of High Mobility Group AT-hook 2 Gene (HMGA2) With the Chromosome 12 Open Reading Frame 42 Gene (C12orf42) in an Aggressive Angiomyxoma With del(12)(q14q23) as the Sole Cytogenetic Anomaly.

ABSTRACT
BACKGROUND/AIM:
Aggressive angiomyxomas are mostly found in the pelvic and perineal region and are prone to recur after surgery. Cytogenetic information is available on only nine such tumors. Herein, we report the cytogenetic anomaly and its molecular consequence in another aggressive angiomyxoma. MATERIALS ANDMETHODS:
An aggressive angiomyxoma found in a 33-year-old woman was examined using cytogenetic, RNA sequencing, reverse transcription polymerase chain reaction (RT-PCR), and Sanger sequencing techniques.RESULTS:
The karyotype of short-term cultured tumor cells was 46,XX,del(12) (q14q23)[9]/46,XX[2]. RNA sequencing detected fusion of the high mobility group AT-hook 2 gene (HMGA2) with the chromosome 12 open reading frame 42 gene (C12orf42). RT-PCR together with Sanger sequencing verified the presence of an HMGA2C12orf42 fusion transcript.CONCLUSION:
The present case carrying del(12)(q14q23) and an HMGA2C12orf42 chimeric transcript strengthens the notion that involvement of HMGA2 and its misexpression are pathogenetically important in the development of aggressive angiomyxomas.Key words
