Common name
H2A histone family, member X 

Potential relevance to the human ageing process

Main reason for selection
Entry selected based on evidence linking the gene product to a pathway or mechanism linked to ageing
Description

Histones such as H2AFX are part of the nucleosome, which consists of DNA wrapped around histones. H2AFX has been involved in DNA repair together with, among others, NBN and TP53 [1004]. H2AFX-null mice were growth retarded and showed signs of genomic instability [1004]. Whether H2AFX plays a role in human ageing remains to be determined.
