Actually inaccurate, the "Turkic/Mongolian" genetic contribution is less than 2-3% to Pakistanis, but spikes in Burushos and Hazaras, though their numbers are not that great to affect the average.
Secondly, this genetic component would be categorized under 'East Asian', not 'Central Asian'. This is highlighted in this data graph.

Our two main components are from Iranian Neolithic Farmers (IVC) and Indo-European migrants (Aryans). This is also similarly shared with NW and High-caste Indians though they have significantly less Indo-European admixture.
When comparing Iron-age samples of the Indus Region (Vedic Age), we can see that genetically not much has changed except for a shift towards Central Asian/Steppe which can be explained by the Scythian/Kushan/Bactrian migrations that occurred.
