Additionally, when these samples from patients with brain metastases were deconvoluted into 30 subtypes, a subtype that was highly enriched in samples from patients with primary NSCLC, with high levels of IFITM3, IFI27, TPM2, and HBG2 reads, was similarly enriched in samples from patients with brain metastases. Here, HBG2 is linked to non-small cell lung carcinoma.
