Description
H4C14 (H4 histone, cluster 4) is a replication-dependent histone H4 gene located in the histone cluster 4 on chromosome 12p12.3. It encodes a core histone protein that is essential for nucleosome assembly and chromatin structure. Histone H4 undergoes extensive post-translational modifications, including acetylation and methylation, which regulate gene expression, DNA repair, and chromosome stability. H4C14 is part of a multigene family with multiple copies across the genome.
Disease Associations
| Disease category | Pathophysiological mechanism | Genomic evidence |
|---|---|---|
| Cancer (various types) | Altered histone H4 expression and mutations may disrupt chromatin structure and gene regulation, contributing to tumorigenesis. | COSMIC lists somatic mutations in H4C14 across multiple cancer types, though specific functional impact is not fully characterized. |
| Immunodeficiency | Mutations in histone H4 genes have been linked to immune dysregulation, but direct evidence for H4C14 is limited. | ClinVar does not currently list pathogenic variants for H4C14. |

Mutations & Variants
Hotspot Mutations
| Variant | Type | Frequency | Functional Description |
|---|---|---|---|
| c.1A>G (p.Met1Val) | Missense | Rare (<0.01%) | Potential loss of start codon, leading to truncated protein. |
| c.95G>A (p.Arg32His) | Missense | Somatic (COSMIC) | May affect histone fold domain, altering nucleosome stability. |
| c.200C>T (p.Thr67Ile) | Missense | Somatic (COSMIC) | Located in histone fold, possible impact on protein interactions. |
Mutation functional classification
Loss of Function (LOF)
Mutations that disrupt the start codon or introduce premature stop codons could lead to reduced histone H4 protein levels, impairing nucleosome assembly and chromatin integrity.
Gain of Function (GOF)
No evidence of gain-of-function mutations for H4C14; histone genes typically act as tumor suppressors, and gain-of-function is not documented.
Dominant Negative (DN)
Mutations in the histone fold domain may produce altered histone H4 proteins that incorporate into nucleosomes, potentially disrupting chromatin structure in a dominant-negative manner, though this is speculative.

Protein Summary
Histone H4 is a highly conserved protein that forms the core of the nucleosome, wrapping DNA into chromatin. It interacts with histone H3, H2A, and H2B to form the octamer. Post-translational modifications, such as acetylation at lysine residues (e.g., K16), regulate chromatin structure and gene expression. H4C14 encodes a replication-dependent histone, expressed during S-phase and incorporated into newly synthesized DNA.
