Entrez ID 3699
Gene name Inter-alpha-trypsin inhibitor heavy chain 3
Gene symbol ITIH3
Synonyms (NCBI Gene)
H3PITI-HC3SHAP
Chromosome 3
Chromosome location 3p21.1
Summary This gene encodes the heavy chain subunit of the pre-alpha-trypsin inhibitor complex. This complex may stabilize the extracellular matrix through its ability to bind hyaluronic acid. Polymorphisms of this gene may be associated with increased risk for sch
