English: Lollipop graph shows mutations in FOLR1 gene reported in literatures. Red star indicates the variant identified in this study. Green dots: missense mutation; Red dots: inframe mutation; Blue dots: Truncating mutation. Green bar: Folate receptor family domain where folate binds. Note: g.3576 T > G splice mutation (from ref. [8]) is not included in this graph due to its being out of the scope after re-annotation
