Variant summary

Our verdict is Likely benign. The variant received -3 ACMG points: 1P and 4B. PP3BS2

The NM_002160.4(TNC):​c.6229C>T​(p.Arg2077Trp) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000031 in 1,613,748 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R2077Q) has been classified as Likely benign.

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]
