Our findings align with studies of newborns with PAE reporting lower diffusivity, but contrast those in older populations with PAE, which consistently report lower FA and higher MD. Further research is needed to understand trajectories of white matter development and how our results of higher FA/lower MD in young children connect with lower FA/higher MD observed at older ages. Currently, there is no biologically based rationale for drug selection in migraine prophylactic treatment. To investigate the genetic variation underlying treatment response to verapamil prophylaxis, we selected 225 patients from a longitudinally established, deeply phenotyped migraine database (N=5983), and collected uninterrupted quantitated verapamil treatment response data and DNA for these 225 cases. We recorded the number of headache days in the four weeks preceding treatment with verapamil and for four weeks, following completion of a treatment period with verapamil lasting at least five weeks. Whole-exome sequencing (WES) was applied to a discovery cohort consisting of 21 definitive responders and 14 definitive non-responders, and the identified single nucleotide polymorphisms (SNPs) showing significant association were genotyped in a separate confirmation cohort (185 verapamil treated patients). Statistical analysis of the WES data from the discovery cohort identified 524 SNPs associated with verapamil responsiveness (p<0.01); among them, 39 SNPs were validated in the confirmatory cohort (n=185) which included the full range of response to verapamil from highly responsive to not responsive. Fourteen SNPs were confirmed by both percentage and arithmetic statistical approaches. Pathway and protein network analysis implicated myo-inositol biosynthetic and phospholipase-C second mess
