Testing of relatives at risk: In the newborn sibs of a proband , it is appropriate to either assay ADA catalytic activity or perform molecular genetic testing (if the family-specific disease-causing mutations are known), so that morbidity and mortality can be reduced by early diagnosis and treatment.

对高危亲属的检测：对先证者的新生同胞兄妹，检测ADA催化活性或进行分子遗传学检测（如果已知家族特异性致病突变）都是合适的，这样早期诊断和治疗便能降低发病率和病死率。

As one of the hereditary marks, it is of useful has somewhat clinical value when there is a proband and the intact pedigree.
