Immunoglobulin heavy variable 3-65 (pseudogene) (IGHV3-65)

Immunoglobulin heavy variable 3-65 (IGHV3-65) is a *pseudogene* in humans that belongs to the immunoglobulin heavy chain variable region gene family. Immunoglobulin variable region genes encode the variable domains of antibody heavy chains, which are crucial for antigen recognition through V-(D)-J recombination and somatic hypermutation, supporting adaptive immune responses. However, IGHV3-65 specifically is classified as a pseudogene, meaning it does **not** encode a functional protein product and is not involved in antibody formation or function[2]. While other IGHV genes have well-established roles in the immune system and in diseases such as various lymphoid malignancies[4][5], IGHV3-65 itself is neither an established therapeutic target, biomarker, nor of clinical pharmacological interest. **Important context:** - IGHV genes in general are involved in B cell receptor diversity and immune recognition[5]. - IGHV3-65 *specifically* is not a protein-coding gene in humans and does not function as a receptor, enzyme, or other drug target[2]. - Closely related IGHV genes and proteins—unlike IGHV3-65—can be relevant to disease and targeted by therapies, but this does **not** extend to IGHV3-65. **Corrections/clarification:** - The name is correct, but it should be noted this is a pseudogene, not a functional protein-coding target in humans[2]. - Thus, most fields requested (drugs, safety, mechanism, biomarkers) are not applicable. - If the intent was to refer to another functional IGHV gene or a general immunoglobulin variable region, the name may be too specific or misplaced for drug targeting.
