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]

TNC links:

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]
