| Remarks |
Clinically affected; diagnosed with epilepsy at age 10 mo.; at age 2 yrs with TS; skin lesions at 10 mo.; height 165 cm and weight 65.3 kg at age 18 yr; numerous adenofibromas about face; shagreen patches; CT scan of brain revealed multiple punctate calcifications along periphery of lateral ventricles, consistent with calcified tubers of TS, parenchymal calcifications noted in right frontal and left temporo-parietal regions, bilobed or mushroom-shaped mass in the region of the left foramen of Monro (~2 x 2.5 cm); renal ultrasound showed numerous bilateral echogenic masses throughout both kidneys, most likely representing angiomyolipomas, associated with TS, the largest measured 3.5 x 2.5 cm; CT scan of kidneys revealed innumerable low density lesions thought out both kidneys, consistent with angiomyolipomas; MRI of the head showed findings consistent with residual or recurrent tumor in the region of the foramen of Monro (subependymal giant cell astrocytoma); son of GM08584; donor subject has a 1 bp insertion at nucleotide 2468 in exon 21 of the TSC2 gene (2468insT) causing a frameshift (Leu823fsX882) |
