Germline Shelterin Loss of Function Predisposes to Lipoma and Uterine Leiomyoma: Population Evidence Bearing on Shelterin-Associated Sarcoma Risk

Germline shelterin loss of function is linked to increased lipoma risk (TERF1 OR 3.32; P = 8.4 x10-) and uterine leiomyoma risk (POT1 OR 2.23; P = 4.0 x 10-).

• Why it matters: It is unclear whether shelterin loss of function, previously tied to sarcoma in a case-enriched cohort, also predisposes to mesenchymal tumors in the general population.
• What they did: Using UK Biobank exome data, rare-variant collapsing tests across five shelterin genes and neoplasm phenotypes were run with Genebass as a second pipeline, with permutation-calibrated statistics and a TP53/RB1/NF1 positive control.
• The result: Lipoma risk increased in TERF1, POT1, and TERF2IP carriers, and uterine leiomyoma risk increased across all four core shelterin genes, with POT1 and TINF2 replicated; sarcoma was not associated, and telomere-lengthening explained POT1 chronic lymphocytic leukemia but not myeloma or TINF2 thyroid cancer.
