Intragenic breakpoint within RAD51L1 in a t(6;14)(p21.3;q24) of a pulmonary chondroid hamartoma

Rearrangements involving chromosome region 14q23-->q24 represent a main cytogenetic subgroup in a variety of benign solid tumors. Recently, in uterine leiomyomas containing the classical t(12;14)(q15;q23-->q24), the primary chromosome 14 target gene was identified as the protein kinase-encoding gene RAD51L1. In this report we show that RAD51L1 is also involved in the frequently occurring t(6;14) (p21;q23-->q24) in pulmonary chondroid hamartomas.
