Abstract
Background
Hereditary leiomyomatosis and renal cell cancer syndrome (HLRCC), caused by heterozygous germline pathogenic variants in the FH, confers an increased risk for cutaneous and uterine leiomyomas and renal cancer.
Methods
About 13,722 advanced cancer patients, including 560 with renal cell carcinoma, had germline analysis performed in the context of tumor‐normal sequencing under an IRB approved protocol.
Results
We report two unrelated individuals with early onset kidney cancer who both carried the c.914C > T (p.Phe305Ser) germline variant in the FH. Both tumors exhibited loss of FH staining by immunohistochemistry and/or positive 2SC staining. Subsequent familial testing discovered that a daughter of a proband who carried the variant had both cutaneous and uterine leiomyomas.
Conclusion
This combination of evidence suggests that the FH c.914C > T (p.Phe305Ser) is pathogenic for HLRCC.
