A Novel MAP3K1 Gene Mutation (c.556A>G) Associated with 46, XY Complete Gonadal Dysgenesis

Zhu Yilin , Chen Hong , He Minfei , Liang Li , Wang Chunlin

Introduction: Complex and ordered intracellular signal pathways play a significant role in sex determination in mammals, mediating the balance of gonadal development. A major pathway involved in the regulation of the male development is mitogen-activated protein kinase (MAPK) signaling pathway. To date, mutations of MAP3K1 gene have been found to account for approximately 15%-20% of 46, XY gonadal dysgenesis (46, XY GD)....

Objective: To determine the mutation in the SRY gene in a 46,XY complete gonadal dysgenesis patient with bilateral gonadoblastoma and coexisting dysgerminoma. Evaluate the functional consequence of mutated SRY gene in the tumor risk of 46,XY DSD.Methods and Materials: The proband was a 13-year-old girl who was admitted for examination due to undeveloped secondary sexual characteristics. She had no breas...
