As hybrids of narrow-line Seyfert 1 (NLS1) galaxies and blazars, {gamma}-ray
emitting NLS1s are important probes of jet physics in the high Eddington-ratio
regime. Only very few of them are known to date; the majority of them below
redshift z = 0.5. Here we present the identification of the {gamma}-ray
emitting AGN TXS 0943+105 (SDSS J094635.06+101706.1) as a high-redshift NLS1
galaxy. It turns out to be one of the radio-loudest NLS1s known, highly
variable at all wavelengths, and shows widely extended radio emission at a
(projected) > 100 kpc scale. It is a known strong {gamma}-ray emitter with a
luminous flare reported previously. At redshift z=1.004, this is the most
distant {gamma}-NLS1 known to date.
