Association of FGD1 polymorphisms with early-onset breast cancer.

ABSTRACT: Recent cancer studies have suggested that the faciogenital dysplasia 1 (FGD1) gene may play a role in the development of tumor cells. Somatic alterations in the FGD1 gene and increased Fgd1 protein expression have been observed in many breast tumor cases. The present study sequenced the FGD1 gene in tumor DNA from 46 breast cancer patients using Ion Torrent sequencing. Three synonymous polymorphisms and one missense polymorphism were detected with next-generation sequencing; however, no somatic mutations were observed. The Thr697 variant was identified in 18 patients with an average age at diagnosis of 55 years, which was a lower average age than patients without the polymorphism. In addition, a higher frequency of Thr697 was observed in African-American patients. The Pro712 was observed i
