Firstly, this is just what you'd expect.

'Limitation'
The study adds to the debate about the role of genes in children's educational attainment, said Dr John Jerrim of the Institute of Education.
But he said the "key limitation" was that the authors "cannot (and do not) tell us which genes are actually thought to influence children's reading and maths ability".
"Until researchers are able to identify the specific genes that are thought to influence children's reading and math skills, and show that such associations are robust in numerous academic studies, then such work has little relevance for public policy," he said.
The quotee knows perfectly well that this is not true.
