Although genetic sequencing of the <jats:italic>AAT<\/jats:italic> gene has only been available for 20 years, analysis of the amount and electrophoretic mobility of the AAT protein has allowed clinical phenotyping for more than 40 years. There have been no studies assessing the psychological impact of having a sib affected by AAT deficiency. Twenty\u2010five participants drawn from the Alpha\u20101 Research Registry completed a questionnaire and semi\u2010structured interview. Respondents were supportive of testing prior to adulthood for AAT status; 18 thought it was a good idea to test a child, three did not know, and four said children should not be tested, primarily citing insurance concerns. Of those 18 who stated it was a good idea, 14 would test at birth. Knowledge of genetics of AAT deficiency was limited; only 44% of respondents understood the inheritance pattern. We recommend: (1) parents and sibs need help in mourning the loss of children with AAT deficiency; young sibs are at risk for trauma and long\u2010term developmental problems. (2) Teams evaluating donors for liver transplantation should be aggressive in ruling out AAT deficiency prior to invasive testing. (3) Testing should be offered to individuals with a family history of AAT deficiency to obtain the health benefits of lifestyle modification and limit the burden of disease discovery in symptomatic relatives. (4) Awareness of liver disease from AAT deficiency should be increased. \u00a9 2004 Wiley\u2010Liss,
