Genes affected

DENR (HGNC:2769): (density regulated re-initiation and release factor) This gene encodes a protein whose expression was found to increase in cultured cells at high density but not during growth arrest. This gene was also shown to have increased expression in cells overexpressing HER-2/neu proto-oncogene. The protein contains an SUI1 domain. In budding yeast, SUI1 is a translation initiation factor that along with eIF-2 and the initiator tRNA-Met, directs the ribosome to the proper translation start site. Proteins similar to SUI have been found in mammals, insects, and plants. [provided by RefSeq, Jul 2008]

Collection Method:clinical testing

The c.95T>C (p.L32P) alteration is located in exon 2 (coding exon 1) of the DENR gene. This alteration results from a T to C substitution at nucleotide position 95, causing the leucine (L) at amino acid position 32 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
