Accumulating evidence suggests that inherited melanoma is not rare and approx. one in seven individuals with melanoma has clinically relevant hereditable cancer-predisposing and/or -susceptibility variant(s). Concerning its germline genetic background, genetic screening aims to identify either variants of predisposing genes with high penetrance or variants of susceptibility genes with medium or low penetrance. However, less attention is paid to genetic testing of germline variants of genes influencing patients' survival outcomes or enhancing the design of new therapies. We aimed to investigate whether the germline genetic background of a Hungarian melanoma cohort ( = 17) contains any pathogenic or likely pathogenic variants of the , , , , , and genes and if the presence of these variants correlate with the clinical findings of the patients, including the advanced stage of melanoma, poor prognosis, and poor survival. We identified three novel variants in the gene and one novel variant in the gene. We detected rapid disease progression, unfavorable outcome, and therapeutic resistance in the patient carrying the likely pathogenic variant. Our study highlights the importance of screening germline variants of genes influencing melanoma progression, therapy resistance, and survival of patients.
越来越多的证据表明,遗传性黑色素瘤并不罕见,大约每七个黑色素瘤患者中就有一个具有临床相关的遗传性癌症易感性和/或敏感性变异。关于其种系遗传背景,基因筛查旨在识别高外显率的易感基因变异或中低外显率的敏感基因变异。然而,对于影响患者生存结果或改进新疗法设计的基因种系变异的基因检测关注较少。我们旨在研究匈牙利黑色素瘤队列(n = 17)的种系遗传背景是否包含BRAF、NRAS、NF1、TP53、CDKN2A和PTEN基因的任何致病性或可能致病性变异,以及这些变异的存在是否与患者的临床发现相关,包括黑色素瘤的晚期、预后不良和生存率低。我们在BRAF基因中鉴定出三个新变异,在NRAS基因中鉴定出一个新变异。我们在携带可能致病性NRAS变异的患者中检测到疾病快速进展、不良预后和治疗耐药性。我们的研究强调了筛查影响黑色素瘤进展、治疗耐药性和患者生存的基因种系变异的重要性。
