Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
Background An expanded spectrum of gain-of-function (GOF) mutations in Ras-related C3 botulinum toxin substrate 2 (RAC2) causes severe combined immunodeficiency (SCID) or combined immunodeficiency (CID), which present with various phenotypes; these immunodeficiencies are characterized by severe lymphopenia, recurrent sinopulmonary infections, bronchiectasis, invasive viral infections, or severe bone marrow hypoplasia. Autoinflammatory features are rarely reported. Method We describe the cases of two girls presenting with novel autoinflammatory phenotypes associated with GOF RAC2 variants. An up-to-date review of the literature was conducted to explore the various spectra of clinical manifestations in patients with GOF RAC2 variants. Results One patient presented with vasculitis and leg ulcers, whereas the other presented with juvenile idiopathic arthritis and severe uveitis. Conclusion Our data extend the spectrum of the clinical presentation of GOF RAC2 variants, which may be associated with autoinflammation, highlighting novel and unusual clinical phenotypes.
