Genes affected

TNC (HGNC:5318): (tenascin C) This gene encodes an extracellular matrix protein with a spatially and temporally restricted tissue distribution. This protein is homohexameric with disulfide-linked subunits, and contains multiple EGF-like and fibronectin type-III domains. It is implicated in guidance of migrating neurons as well as axons during development, synaptic plasticity, and neuronal regeneration. [provided by RefSeq, Jul 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 -16 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.010558158).
• BP6: Variant 9-115021264-C-T is Benign according to our data. Variant chr9-115021264-C-T is described in ClinVar as [Likely_benign]. Clinvar id is 805677.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr9-115021264-C-T is described in Lovd as [Likely_benign].
• BS2: High AC in GnomAd4 at 390 AD gene.
