Since it's quite an esoteric subject of matter and with work on it being done at the best gradually to my knowledge it. It is known that if the Hodge conjecture is true, then the locus of all points on the base where the cohomology of a fiber is a Hodge class is in fact an algebraic subset, that is, it is cut out by polynomial equations.

This construction, along with Borel’s Extension Theorem, provides the conduit to apply Hodge theory to study the moduli spaces (and their compactifications) of principally polarized abelian varieties and K3 surfaces. This conjecture is known to be false, hence the refinement of the Hodge conjecture to rational cohomology classes. The Hodge Conjecture states that every Hodge class of a non singular projective variety over $\mathbf{C}$ is a rational linear combination of cohomology classes of algebraic cycles: Even though I'm able to understand what it says, and at first glance I do find it a very nice assertion, I cannot grasp yet why it is so relevant as to be.

Abstract: Hodge cycles are topological cycles which are conjecturally (the millennium Hodge conjecture) supported in algebraic cycles of a given smooth projective complex manifold. To call it a “theory” is simply to say that it’s the study of some particular thing, just as you could say that “right triangle theory. We also present the definitional proof that Hodge can define a conjecture statement "Hodge class is a rational linear combination of classes cl(Z) of algebraic cycles" that is provable as that is how he is defining the problem and he can conjecture something as a statement of proof.
