Clinical summary of patients with FAM161A mutations associated with retinitis pigmentosa.

aVisual Acuity: best corrected Snellen visual acuity.bElectroretinograms: full field cone ERG amplitude in microvolts to 30HZ white light (lower norm = 50 microvolts).cVisual Field: Goldmann total field area to V-4e white test light (lower norm = 11,399 degrees squared).dDark adaptation: final threshold in log units above normal after 45 minutes of dark adaptation.eLens: −, clear lens; +, central posterior subcapsular cataract.fMacula: −, within normal limits; +, granular.gPeriphery: bone spicule or clumped pigment in one or more quadrants: +, present; −, absent.Abbreviations: F, female; M, male; EO, ethnic origin; OD, right eye; OS, left eye; HM, hand motions; PP, pseudophakia; AS, atrophic scar; NA, not available.
