We also identified a group of candidate haplotypes (∼51 kb) in COL24A1, the frequency of which is higher in PNG (0.47), MLS (0.31), Vellalar (an nNL-TIA population in South Asia; 0.28), CheWong (an nNL-TIA population in Southeast Asia; 0.25), Tibetan (0.20), and African populations (0.25–0.42) than the rest of populations studied. Here, COL24A1 is linked to transient ischemic attack.
