Association of Polygenic Score With Tumor Molecular Subtypes in Papillary Thyroid Carcinoma

J Clin Endocrinol MetabPublished Cross-sectional study

Authors' conclusion

PGS has molecular subtype-specific associations in PTC, which has implications for their use in risk prediction.

Study context

Population
Patients with papillary thyroid carcinoma (PTC) in The Cancer Genome Atlas (TCGA) thyroid cancer study
Participants
359 patients
Exposure
Polygenic score (PGS) association with PTC molecular subtypes
Outcome
Association of germline genetic risk (10-single-nucleotide variation PGS) with PTC molecular subtypes defined by tumor driver mutation status
Methodological detailsTCGA thyroid cancer data, polytomous logistic regression
  • TCGA thyroid cancer data
  • Polytomous logistic regression

Main finding

As reported in the abstract

PTC molecular subtype by tumor driver mutation status
  • PGS significantly associated with specific tumor molecular subtypes defined by driver mutation status
  • Increasing germline risk associated with higher odds of BRAFV600E-mutated PTC vs "other"
  • No significant difference in PGS for RAS subtype vs BRAFV600E

Observational data: associations, not effects.

Further findings

Exploratory: Messenger RNA (mRNA)-, microRNA- and DNA methylation-defined molecular subtypes

PGS also associated with mRNA-, microRNA- and DNA methylation-defined subtypes
  • Exploratory analyses
