Immunoglobulin heavy locus (IGH) is a gene that encodes for a variable region in immunoglobulins, protein complexes that recognize foreign antigens and initiate immune responses. It is not clear whether IGH mutations have been observed in human cancers.

IGH is altered in 0.62% of all cancers with diffuse large B-cell lymphoma, not otherwise specified, follicular lymphoma, mature B-cell neoplasm, breast invasive ductal carcinoma, and chronic lymphocytic leukemia/small lymphocytic lymphoma having the greatest prevalence of alterations [3].

IGH GENIE Cases - Top Diseases

The most common alterations in IGH are IGH Fusion (0.32%), IGH-BCL2 Fusion (0.29%), IGH-MYC Fusion (0.23%), IGH-CCND1 Fusion (0.15%), and IGH-FGFR3 Fusion (0.08%) [3].
