Narrative:

Flight planned to las via the grnpa one RNAV arrival. Neither the flight plan nor the FMC had the luxor intersection between the ksino intersection and the grnpa intersection. Luxor has both a crossing restr and an airspeed restr; and is not on a straight line between ksino and grnpa. Both flight plan and FMC data displayed ksino direct to grnpa. As the paper flight plan agreed with the FMC programmed arrival procedure; I am fairly certain that we did not make a data entry or programming error. I do not know if this was a one time glitch; or if the luxor intersection is being omitted from all flight plans and FMC arrival programming. Please check to avoid a deviation or worse.
