| Summary:
Fast radio bursts (FRBs) are one of the most exciting new mysteries of
astrophysics. Their origin is still unknown, but recent observations seems to
link them to Soft Gamma Repeaters and, in particular, to magnetar giant flares
(MGFs). The recent detection of a MGF at GeV energies by the textit{Fermi}
Large Area Telescope (LAT) motivated the search for GeV counterparts to the
>100 currently known FRBs. Taking advantage of more than 12 years of
textit{Fermi}-LAT data, we perform a search for gamma-ray emission from all
the reported repeating and non-repeating FRBs. We analyse on different-time
scales the textit{Fermi}-LAT data of each individual source separately,
including a cumulative analysis on the repeating ones. In addition, we perform
the first stacking analysis at GeV energies of this class of sources in order
to constrain the gamma-ray properties of the FRBs that are undetected at high
energies. The stacking analysis is a powerful method that allow a possible
detection from below-threshold FRBs providing important information on these
objects. In this talk we present the preliminary results of our study and we
discuss their implications for the predictions of gamma-ray emission from this
class of sources
