Abstract

Genetic counselling for Gaucher's disease requires a comprehensive approach, including accurate diagnosis at both the enzymatic and molecular levels, and assessment of disease severity. These goals are particularly challenging given the great allelic and phenotypic heterogeneity encountered in this disorder. Counselling should address the specific concerns of the counsellee, which may be related to evaluation of an affected person, or to reproductive options in couples at risk. Advances in both diagnosis and treatment have led to increased ascertainment of cases and carriers through population based screening, rather than through affected probands, raising new ethical and medical dilemmas. This chapter outlines practical issues in counselling for the various forms of Gaucher's disease, based on current data and experience.

戈谢病:遗传咨询和人群筛查
戈谢病的遗传咨询需要全面的方法,包括在酶和分子水平上的准确诊断,以及对疾病严重程度的评估。这些目标尤其具有挑战性,因为在这种疾病中遇到了巨大的等位基因和表型异质性。咨询应解决咨询人员的具体关切,这些关切可能与对受影响者的评价有关,也可能与处于危险中的夫妇的生殖选择有关。诊断和治疗方面的进步导致通过基于人群的筛查而不是通过受影响的先证者来更多地确定病例和携带者,从而引发了新的伦理和医学难题。本章根据目前的数据和经验,概述了各种形式戈谢病咨询的实际问题。
