This paper introduces the related concepts and methods of survival analysis and QTL mapping in detail. This study uses accelerated failure time model for Bayesian QTL mapping, combining the survival analysis and biometrical genetics, and studies on the principle of Bayesian mapping analysis for Genomic Architecture of Survival Traits based on the accelerated failure time model.

2The involvement of MFT in woman is more than that in man.(3)The patients showed multiple dome-shaped, skin-colored, firm papules on the face. Some patients also present the lesions on the scalp and neck. No lesion showed the malignant tendency.(4) The histologic findings of MFT are cornified cysts and some nests of basaloid epithelial cells.(5)There were variable clinical expressions in different patients of the same family.(6) Some pedigrees were also affected by feckle or symmetrical progressive erythrokeratoderma, which were not found in MFT patients of other origin.

MFT临床分析总结：①MFT遗传方式为常染色体显性遗传；②女性发病多于男性；③中国汉族人MFT的典型皮损特征为面部乳白色半球形或圆锥形丘疹，质地坚实，只有2个家系皮损分别发生于头皮及颈部，均无恶化倾向；④组织病理特征为角质囊肿和由基底样瘤细胞构成的肿瘤岛；④同一家系中不同的患者表现度不同；⑤个别家系可伴发雀斑及进行性对称性红斑角化症，其它家系不伴发其他疾病。
