Mycobacterium avium causes
infections in immunocompromised individuals. Recurrent infection with
this organism has been associated with a deletion at the 818 residue of
the interferon-
receptor (IFN-
R). This mutation produces a
truncated receptor without an intracytoplasmic tail, resulting in
diminished signaling. We describe a substitution at the 832 residue of
the IFN-
R causing a similar truncated receptor in a 7-year-old girl
with recurrent M avium osteomyelitis.
