White matter tracts most relevant in distinguishing individual phenotype I patients from phenotype II patients using the Elastic Net algorithm.
| Rank | Anatomical region | MNI Coordinates (x, y, z) | Cluster size | *Average beta weight | Beta % |

| 1 | IFOF | -31, 35, 11 | 92 | -5.778 | 6.56% |
| 2 | Mid colossal pathways | -22, -30, 43 | 79 | 4.379 | 4.97% |
| 3 | Isthmus of the corpus callosum | -22, -52, 33 | 104 | 3.849 | 4.37% |

IFOF – inferior fronto-occipital fasciculus, MFCC – minor forceps of the corpus callosum.
Beta weights were averaged within the cluster. Anatomical regions are listed based on absolute average beta weight within the cluster. Negative beta weights indicate FA reductions in phenotype II patients as compared to phenotype I
