TAF12, NFYC, and RAD54L co-located on human chromosome 1p32-35.3 and mouse chromosome 4qD1-D3 were identified as oncogenes that are gained in tumors in both species and required for disease initiation and progression.
We used PCR/SSCP to examine all 18 exons of the hRAD54 gene for mutations in 25 tumors, but the mobility shifts detected corresponded to previously identified polymorphic changes: T-to-C transition at nucleotide 2865 (with no amino acid change) and at nucleotide 3008, at the 3' untranslated region.
The hRAD54 gene is related to a family of genes involved in DNA recombination and repair and encodes a protein with DNA helicase activity. hRAD54 has been mapped to 1p32, a region frequently involved in deletions in a variety of tumor types, including atypical and anaplastic meningiomas.
