In a genome‐wide association study of never smokers with non‐small cell lung carcinoma (NSCLC), genetic variants were shown to significantly correlate with the expression levels of several genes – including ATXN7L2 – in normal lung tissue. Moreover, ATXN7L2 was found to be markedly differentially expressed between tumor and adjacent normal tissue, suggesting that altered regulation of ATXN7L2 may be linked to patient survival and thus serve as a novel prognostic marker in NSCLC."}, {"type": "fg", "children": [{"type": "fg_f", "ref": "1"}]}, {"type": "t", "text": ""}]}, {"type": "t", "text": "\n \n "}, {"type": "p", "children": [{"type": "t", "text": "\n Although the detailed molecular function of ATXN7L2 remains to be fully elucidated, its candidacy as a prognostic factor in lung cancer is reinforced by a broader context in which proteins from the ataxin family have been implicated in key cellular processes.
