PSEN2 and nasopharyngeal carcinoma: Although we observed single NPC cases with variants in PSEN2 (p.His169Asn), BRD2 (p.Glu762Asp), and CLPTM1L (p.Arg510Trp), there was insufficient evidence for further support for any of the candidate genes/variants given the small sample sizes of these publicly available NPC WES datasets.
