Genes affected

TNFSF8 (HGNC:11938): (TNF superfamily member 8) The protein encoded by this gene is a cytokine that belongs to the tumor necrosis factor (TNF) ligand family. This cytokine is a ligand for TNFRSF8/CD30, which is a cell surface antigen and a marker for Hodgkin lymphoma and related hematologic malignancies. The engagement of this cytokine expressed on B cell surface plays an inhibitory role in modulating Ig class switch. This cytokine was shown to enhance cell proliferation of some lymphoma cell lines, while to induce cell death and reduce cell proliferation of other lymphoma cell lines. The pleiotropic biologic activities of this cytokine on different CD30+ lymphoma cell lines may play a pathophysiologic role in Hodgkin's and some non-Hodgkin's lymphomas. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Nov 2011]

DELEC1 (HGNC:23658): (deleted in esophageal cancer 1) The function of this gene is not known. This gene is located in a region commonly deleted in esophageal squamous cell carcinomas. Gene expression is reduced or absent in these carcinomas and thus this is a candidate tumor suppressor gene for esophageal squamous cell carcinomas. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.87).
• BA1: GnomAd4 highest subpopulation (AMR) allele frequency at 95% confidence interval = 0.444 is higher than 0.05.
