LRRK2 and non-small cell lung carcinoma: By querying the OncoKB database [51,52] for genes located at 12q12, only ARID2 deletion was found to be likely oncogenic, specifically in non-small cell lung cancer [53] and hepatocellular carcinoma [54]; in our analysis, ARID2 whole gene deletion co-occurred in 14.53% of LRRK2 CNV-altered cases.
