BRCA Gene Mutations Now Linked to Thyroid, Bladder, Skin and Head-Neck Cancers

An international research team led by the RIKEN Center for Integrative Medical Sciences in Japan has discovered that pathogenic variants of BRCA1 and BRCA2 genes are associated with four additional cancer types beyond the previously known breast and ovarian cancers: thyroid, bladder, skin, and head-neck cancers. The findings, published in ESMO Open, expand the potential for personalized medicine approaches to several cancer types that currently have limited treatment options and poor prognoses. This discovery represents a significant advancement in understanding genetic cancer risk factors and could inform new screening and treatment strategies for patients carrying BRCA gene mutations.

Expansion of BRCA gene mutations to new cancer types

• ▪Pathogenic variants of the BRCA 1 and 2 genes are now linked to thyroid cancer.
• ▪An international group led by researchers from the RIKEN Center for Integrative Medical Sciences in Japan discovered associations between pathogenic variants of the BRCA 1 and 2 genes and four types of cancer.
• ▪The findings on BRCA 1 and 2 gene associations with thyroid, bladder, skin and head-neck cancers were published in ESMO Open.

Implications for personalized cancer treatment

• ▪The findings on BRCA 1 and 2 gene associations expand the potential for personalized medicine to several cancer types that currently have limited treatment options.
• ▪The cancer types newly associated with BRCA 1 and 2 gene mutations currently have poor prognoses.

Perspective of RIKEN Center for Integrative Medical Sciences researchers

• ▪The researchers view the newly discovered BRCA1 and BRCA2 associations as significant for cancers with poor prognoses.
• ▪The RIKEN-led research team believes their BRCA gene findings expand personalized medicine potential to cancer types with limited treatment options.
