DNA ANALYSES Sequence analysis has identified a frameshift (-ACC) at codon 38 or 39 of the alpha1 gene
FUNCTION STUDIES Unknown
STABILITY Unstable
OCCURRENCE Found in a few Arabian families in Israel
OTHER INFORMATION Quantity in the heterozygote not known; occurred in combination with a nondeletional alpha-thal; homozygosity has been described; this person suffered from severe hemolytic anemia
