analysis of the data in the present and two other reported families indicates that abl can result from the homozygous inheritance of the same gene which , when present in the heterozygous state , results in hbl't is concluded , therefore , that these cases of abl have apparently been inherited via a different genetic mutation than most previously reported cases of abl , and is likely the same gene involved in hbl .
