Disseminated Intravascular Coagulation Associated with Large Deletion of Immunoglobulin Heavy Chain.

ABSTRACT

Although the majority of monogenic defects underlying primary immunodeficiency are microlesions, large lesions like large deletions are rare and constitute less than 10% of these patients. The immunoglobulin heavy chain (IGH) locus is one of the common regions for such genetic alterations. This study describes a rare case of autosomal recessive agammaglobulinemia with a homozygous large deletion in chromosome 14q32.33 (106067756-106237742) immunoglobulin heavy chain clusters with an unusual and severe skin infection and disseminated intravascular coagulopathy.
