腫瘤治療檢測基因臨床應用結果

有效雄激素不敏感綜合征 (CAIS) 是一種罕見的遺傳病，由雄激素受體 (AR) 基因突變導致目標問題對雄激素產生抗性，并在基因男性個體中出現(xiàn)女性表型。一名表型為女性的 16 歲患者因原發(fā)性閉經就診于我們的診所。她的臨床評估顯示女性外生殖器正常，Tanner III 乳房發(fā)育，陰毛和腋毛稀疏（Tanner II 期）。荷爾蒙評估顯示促黃體激素 (LH)、睪酮和抗苗勒管激素 (AMH) 的濃度增加。圖像研究未檢測到子宮或性腺，但陰道盲，核型為 46，XY。這些發(fā)現(xiàn)表明 CAIS 的診斷，并且 AR 基因的基因檢測揭示了胞嘧啶到腺嘌呤 (c.2612C>A) 的罕見致病性突變，在 AR 中的位置 871 (p.Ala871Glu) 將丙氨酸替換為谷氨酸，如前所述一次在兩個成年姐妹中?；颊呓邮芰诵韵偾谐g并接受了激素替代治療。本研究擴展了 AR 突變數據庫，顯示了 CAIS 患者及時診斷、適當管理和隨訪的復雜性和重要性，強調了標準化方案的必要性。關鍵詞：CAIS；派斯；雄激素受體；有效雄激素不敏感綜合征；激素替代療法；突變。

腫瘤發(fā)生與革命國際數據庫描述：

Complete Androgen Insensitivity Syndrome (CAIS) is a rare genetic condition by mutations in the androgen receptor (AR) gene resulting in target issue resistance to androgens and a female phenotype in genetically male individuals. A 16-year-old phenotypically female individual presented to our clinic with primary amenorrhea. Her clinical evaluation showed normal female external genitalia, Tanner III breast development and sparse pubic and axillary hair (Tanner stage II). Hormonal assessment revealed increased concentrations of Luteinizing Hormone (LH), Testosterone and Antimüllerian Hormone (AMH). Image studies detected no uterus or gonads, but a blind vagina and the karyotype was 46, XY. These findings suggested the diagnosis of CAIS, and genetic testing of the AR gene revealed a rare pathogenic mutation of cytosine to adenine (c.2612C>A) replacing alanine with glutamic acid at position 871 (p.Ala871Glu) in the AR, previously described once in two adult sisters. The patient underwent gonadectomy and received hormonal replacement therapy. This study expands the AR mutation database and shows the complexity and the importance of prompt diagnosis, proper management, and follow-up for CAIS patients, underlining the need for standardized protocols.Keywords:?CAIS; PAIS; androgen receptor; complete androgen insensitivity syndrome; hormone replacement therapy; mutation.
