Investigating the association of rs2910164 with cancer predisposition in an Irish cohort
McVeigh et al.
The finding, in our words
In an Irish cohort of 1516 participants, the rs2910164 variant in MIR146A was significantly associated with differentiated thyroid cancer (per allele OR = 1.59, P = 0.002) but not breast cancer. DNA extracted from saliva collected using Oragene 575 kits yielded successful genotyping, supporting decentralised screening for cancer predisposition.
A paraphrase to the Library’s standard, never the abstract. The source is one link away and is always the authority.
Using the Oragene saliva device, this study identified elevated CYP2C8 allele frequencies in a Saudi paediatric cohort compared to other Asian populations, suggesting potential variability in ibuprofen metabolism and drug response.
Using the Oragene Discovery 500 series for decentralised saliva collection in 524 African American adolescents, this study found that positive neighbourhood conditions relate to fewer behavioural difficulties, despite genetic risk. The authors note that most gene-environment studies of behaviour use European ancestry samples, limiting generalisability to African American youth.
Using patient-centric saliva microsampling with the Oragene kit, the study found a low overall prevalence, 13%, of the OPRM1 118G allele in a Western Saudi population, with a significantly higher frequency in females, 21%, than males, 5%. The authors note the findings are specific to this population and may not be generalisable.
The study found that the Oragene OG-600 receptacle provided the highest concentration of salivary DNA, including short fragments suitable for analysis, and successfully detected HPV DNA from patient saliva. This matters for decentralised sampling as it supports the use of a standardised, self-collection device for non-invasive cancer biomarker detection.
Self-collected saliva samples provided adequate DNA for genotyping in preterm birth research, though questionnaire data on birth details had limited concordance with prospective records, indicating that while DNA sampling is feasible via post, phenotyping requires more reliable data collection methods for genetic studies.
