FIG. 4.
T1-weighted mid-sagittal and coronal and T2-weighted axial images of a normal patient (A–C) and Patient 1 (LR#07-155a1, D-F), T1-weighted mid-sagittal and T2-weighted axial and coronal images of Patient 2 (LR07-155a2, G–I), T1-weighted mid-sagittal and coronal and T2-weighted axial images of Patient 3 (LR10-168, J–M). Note obvious microcephaly, low-sloping forehead, with diffusely reduced number of gyri, shallow wide sulci consistent with microcephaly with simplified gyri, as well as moderately enlarged extra-axial space and thin cortex in all affected patients.
