So there is no a full quantum theory of gravitation. However, there are instances where quantum effects due to gravitation have been studied. Like Gravitational neutron interferometry https://arxiv.org/pdf/1701.00259.pdf or maybe gravitational decoherence https://www.nature.com/articles/nphys3366
I would like to know if there are others quantum effects that involve gravity that can (at least in an approximate way) be studied without a full quantization of gravity.
