Readings

One paper per session for the first six journal clubs, starting in familiar primary care territory and working toward rare disease. Presenters can swap in their own pick. Sessions two and six are case sessions: the paper frames the discussion, the cases carry it.

SessionThemeReadingWhy this one
1Family history as a diagnostic toolRitchie JB, et al. Public Health Genomics 2022. doi:10.1159/000520001Primary care clinicians matched hereditary-cancer referral guidelines 60.6% of the time versus 82.2% for genetic counselors; a family-history tool closed the gap.
2The patient who didn't fitForghani I, et al. Genes 2025. doi:10.3390/genes16050530Of 178 patients meeting hEDS criteria, genetic testing found an alternative or additional diagnosis in 26.4%. Each member brings a one-paragraph outlier patient.
3Familial hypercholesterolemiaJones LK, et al. Front Health Serv 2023. doi:10.3389/frhs.2023.1104311 Companion: Morgan KM, et al. Public Health Genomics 2026. doi:10.1159/000552982Why FH stays underdiagnosed, and what a primary-care cascade-testing program looks like.
4Pharmacogenomics in everyday prescribingEl Rouby N, Johnson JA. NEJM Evidence 2025. doi:10.1056/EVIDra2400343Current evidence, barriers and adoption pathways for PGx testing, including primary care.
5Hereditary cancer risk beyond BRCAPederson HJ, Narod SA. BJC Reports 2024. doi:10.1038/s44276-024-00099-xThirty years after BRCA, most carriers remain unidentified; the barriers include primary care unfamiliarity.
6The undiagnosed patientPitsava G, et al. Genetics in Medicine 2025. doi:10.1016/j.gim.2025.101574Genome sequencing found a diagnosis in 54 of 353 undiagnosed families (15.3%); over half of the causal variants sat in regions earlier tests never looked at. A long diagnostic odyssey is presented.

For the hypermobility cohort channel: Aziz Q, et al. AGA clinical practice update on GI manifestations and autonomic or immune dysfunction in hypermobile Ehlers-Danlos syndrome. Clin Gastroenterol Hepatol 2025. doi:10.1016/j.cgh.2025.02.015. Sixteen best-practice statements, and the most useful single document on the POTS and mast cell questions that come up in every hypermobility clinic.

After session six, the group sets the next run together, including at least one session on the ethics and economics of independent practice.
