身材矮小是儿童时期常见的症状,其病因复杂,部分患者伴有智力低下、特殊面容、多系统发育缺陷等表现。染色体畸变、拷贝数变异(copy number variants,CNV)、核基因组或线粒体基因组致病性变异、表观遗传修饰异常等均可能引起复杂表型[1...身材矮小是儿童时期常见的症状,其病因复杂,部分患者伴有智力低下、特殊面容、多系统发育缺陷等表现。染色体畸变、拷贝数变异(copy number variants,CNV)、核基因组或线粒体基因组致病性变异、表观遗传修饰异常等均可能引起复杂表型[1]。因此,对于严重的或不明原因的身材矮小,特别是合并其他复杂表型的患者,采用遗传学检测辅助病因诊断至关重要。展开更多
