SNPs modeled as wildcards can lead to more informed and biologically relevant alignments. We improve the space complexity of previous approaches by giving a succinct index requiring $(2 + o(1))n \\log \\sigma + O(n) + O(d \\log n) + O(k \\log k)$ bits for a text of length $n$ over an alphabet of size $\\sigma$ containing $d$ groups of $k$ wildcards.
