Abstract
Neonatal identification of children at high somatic risk due to inherited .alpha.1 antitrypsin deficiency (ATD) elicits a negative emotional reaction in a majority of the parents, at least initially. This sub-study was conducted to determine whether the identification and follow-up of the children''s ATD had negatively influenced the families'' reproduction, marital status and social class level (defined by parental occupation) during the 5 yr following the identification of the children''s ATD. No such negative effects were found in comparing these characteristics among 61 families with a child with ATD vs. 183 control families living in the same area and having a child of the same sex and age. Unexpectedly, the ATD-children''s families (fathers) had a significantly higher social class level, raising the question of a possible gene advantage associated with ATD.
