Recent studies of rare b-hadron decays have revealed a coherent pattern of deviations from Standard Model predictions in b→ sl+l- transitions, known as flavour anomalies. Rare charm decays that may proceed through c→ ul+l- flavour-changing neutral-current processes offer the unique and complementary opportunity to search for anomalies in the up-type quark sector that has hardly been explored in the past. For long, rare charm decays have been considered as less promising due to difficulties in the description of its low energy dynamics. During this talk, I will discuss how exact or approximate symmetries in the charm system allow to construct clean null-test observables, yielding an excellent road to the discovery of New Physics. Special focus will be on recent results by the LHCb collaboration from the first full angular analysis of a rare charm decay.
