Mutational analysis (c.402C}G) of the FOXL2 gene and immunohistochemical expression of the FOXL2 protein in testicular adult type granulosa cell tumors and incompletely differentiated sex cord stromal tumors

Abstrakt

Recently a somatic point mutation in the FOXL2 gene has been characterized in ovarian adult type of granulosa cell tumor (ATGCT) (94.6%), thecomas (12.5%), but not in juvenile type of ovarian granulosa cell tumor, other ovarian sex cord tumors and ovarian surface epithelial neoplasms. Whether this mutation is present in testicular ATGCT or incompletely differentiated sex cord stromal tumor (ISCST) is not known.
