OBJECTIVE: To describe a case of a personal and family history of early uterine leiomyomatosis that revealed a pathogenic variant in the FH gene encoding fumarate hydratase. After the patient's diagnosis, a first-degree relative was detected with early-stage renal cell carcinoma. The patient decided to undergo preimplantation genetic testing to reduce the risk to her future children.
DESIGN: A case report of autosomal dominant hereditary leiomyomatosis and renal cell cancer syndrome where the patient underwent 2 cycles of in vitro fertilization with preimplantation genetic testing for monogenic disease/aneuploidy (PGT-MA) that resulted in 3 unaffected, euploid embryos.
SETTING: Large academic single-center hospital.
PATIENTS: A 35-year-old nulligravida woman with a personal history of an early-onset uterine leiomyomatosis and a family history of renal cell carcinoma and uterine leiomyomas, who is heterozygous for a pathogenic variant in FH and diagnosed with hereditary leiomyomatosis and renal cell cancer syndrome. Informed consent was obtained.
INTERVENTIONS: Two laparoscopic myomectomies were performed, and tissue was sent for histopathology and immunostaining. Hereditary leiomyomatosis and renal cell cancer syndrome was confirmed by germline testing, and 2 cycles of PGT-MA were performed.
MAIN OUTCOME MEASURES: Through PGT-MA, the patient was able to mitigate the risk of passing a known familial variant to her future children.
RESULTS: After 2 cycles of in vitro fertilization with PGT-MA, 3 unaffected embryos were available for transfer. An unaffected, euploid embryo was transferred for pregnancy, and the patient is currently pregnant in her second trimester.
CONCLUSIONS: Pathogenic variants in FH should be suspected in patients with early-onset uterine leiomyomas and a family history of cutaneous and/or uterine leiomyomas. Familial variant testing is crucial in identifying relatives at risk to start early screening.
