Tuberous sclerosis complex (TSC) is an autosomal dominant disease associated with tumors and malformed tissues in the brain and other vital organs. We report a novel de novo frameshift variant of the TSC1 gene (c.434dup;p. Ser146Valfs*8) in a child with TSC who initially presented with a sacral teratoma. This previously unreported association between TSC and teratoma has broad implications for the pathophysiology of embryonic tumors and mechanisms underlying cellular differentiation.
结节性硬化症（TSC）是一种常染色体显性疾病，与大脑及其他重要器官中的肿瘤和组织畸形有关。我们报告了一名患有TSC的儿童，其TSC1基因出现了一种新的从头移码变异（c.434dup；p.Ser146Valfs*8），该患儿最初表现为骶尾部畸胎瘤。TSC与畸胎瘤之间这种先前未报道的关联，对胚胎肿瘤的病理生理学以及细胞分化的潜在机制具有广泛影响。
