PTPRD and glioblastoma: Also, a PTPRD germline variant (p.C1428G) was identified exclusively in smoker patients among Brazilian non-small-cell lung cancer patients (Couto et al., 2017) and a partial deletion (9p23 (9101605_9521604)x1) in PTPRD is suspected to have predisposed a child for developing glioblastoma (Gambale et al., 2019), but clearly more data is needed to corroborate the gene’s candidacy as a cancer susceptibility gene.
