摘要

端粒生物学疾病（TBD）是一组以端粒短小为特征的复杂遗传性疾病。先天性角化不良症（DC）目前被认为是一种严重的 TBD 表型，其特征是网状色素性改变、指甲营养不良、口腔白斑病前期恶变和全身受累。本病例描述了一名患有网状色素性变化和特里氏指甲的 2 岁女性，她被发现患有 TERT 变异和端粒短；她没有 TBD 的其他粘膜和全身特征。本报告描述了 TBD 的一种独特临床表现，并强调了在典型 DC 特征有限或不明显的个体中坚持怀疑 TBD 的重要性。

Reticulated pigmentary changes and Terry's nails in a patient with a TERT variant-associated telomere biology disorder.

Telomere biology disorders (TBD) are a complex set of inherited illnesses characterized by short telomeres. Dyskeratosis congenita (DC), which is now considered a severe TBD phenotype, is characterized by reticulated pigmentary changes, nail dystrophy, premalignant oral leukoplakia, and systemic involvement. This case describes a 2-year-old female with reticulated pigmentary changes and Terry's nails who was found to have a TERT variant and short telomeres; she lacked other mucocutaneous and systemic features of TBD. This report describes a unique clinical presentation of TBD and highlights the importance of upholding suspicion for TBD in individuals with limited or subtle features of classic DC.
