Family with sequence similarity 223 member B (non-protein coding) (FAM223B)

Family with sequence similarity 223 member B (FAM223B) is classified as a long intergenic non-protein coding RNA (lincRNA), implicated in gene regulation at the transcriptional, post-transcriptional, or epigenetic level[3][4][8]. FAM223B is a non-protein coding gene also referred to as LINC00204B, encoding a lincRNA transcript rather than a protein. While lincRNAs can control gene expression programs and have roles in development, cell differentiation, and disease states, there is no direct evidence for a therapeutic target function or specific disease association for FAM223B. Current knowledge does not establish FAM223B as involved with drug mechanisms, biomarker selection, or clinical safety challenges[3][4][8]. Note: Some of the aliases and database entries may contain closely related gene symbols typical for non-coding RNA annotation, but no conflicts or major errors are detected in the form or spelling of this target. FAM223B is indexed as a non-protein coding gene, not as a receptor, enzyme, or other canonical drug target class[3][4][8].
