Outcome Measures
Primary Outcomes (2)
Rate of cancer amongst carriers of CTNNA1 loss-of-function variants
After collecting personal and family cancer history from enrolled participants, family pedigrees will be utilized to calculate cancer risk estimates for for CTNNA1 loss-of-function variant carriers including gastric cancer risk, breast cancer risk, as well as risk of other cancers currently not known to be associated with CTNNA1 variants gene.
Through study completion, which will average 1 year
Number of CTNNA1 genotypes associated with a cancer phenotype
Using collected family pedigrees from enrolled participants, we will correlate estimated cancer risk for CTNNA1 loss-of-function variant carriers with their CTNNA1 genotype, to determine if there is a significant genotype-phenotype correlation observed.
Through study completion, which will average 1 year
Interventions
Personal medical and genetic history, as well as relevant information about family history, will be collected from participants in the CAFÉ Study through an online data entry system
Eligibility Criteria
The CAFÉ Study will recruit individuals who carry a germline CTNNA1 loss-of-function variant as well as first degree relatives of germline CTNNA1 loss-of-function variant carriers.
You may qualify if:
- years of age and older
- Participants must be carrier, or a first degree relative of a carrier, of a CTNNA1 loss-of-function variant defined as: a variant predicted to lead to protein truncation (nonsense and frameshift variants), a large deletion of one or more exons, or a consensus splice site variant predicted to disrupt splicing in CTNNA1. CTNNA1 loss-of-function variants do not need to be classified as pathogenic or likely pathogenic to be included.
- Participants must be able to understand and read English
- Participants must be able to provide informed verbal or written consent
You may not qualify if:
- Less than 18 years of age
- Individuals who do not carry a CTNNA1 loss-of-function variant and are not a first degree relative of a CTNNA1 loss-of-function variant carrier.
- Individuals who cannot speak and read English
- Major psychiatric illness or cognitive impairment that in the judgement of the study investigators or study staff would preclude study participation
- Unable to comply with the study procedures as determined by the study investigators or study staff
