Abstract
We report a case of a male fetus with early-onset macrosomia and a pathogenic variant in PTEN identified on a macrocephaly and overgrowth sequencing panel. The pregnancy ended at 25 weeks gestation. On post-mortem examination, macrosomia was confirmed, and maturation of the brain was approximately 3 weeks ahead of that of the visceral organs. There was microscopic evidence of gonadoblastoid dysplasia, which is an extremely rare finding and has never been associated with PTEN hamartoma tumor syndrome (PHTS). To our knowledge, this is the first report of a prenatal phenotype with a heterozygous germline variant in PTEN.

Prenatal Diagnosis welcomes submissions in all aspects of prenatal diagnosis with a particular focus on areas in which molecular biology and genetics interface with prenatal care and therapy, encompassing: all aspects of fetal imaging, including sonography and magnetic resonance imaging; prenatal cytogenetics, including molecular studies and array CGH; prenatal screening studies; fetal cells and cell-free nucleic acids in maternal blood and other fluids; preimplantation genetic diagnosis (PGD); prenatal diagnosis of single gene disorders, including metabolic disorders; fetal therapy; fetal and placental development and pathology; development and evaluation of laboratory services for prenatal diagnosis; psychosocial, legal, ethical and economic aspects of prenatal diagnosis; prenatal genetic counseling
