Genes affected

NMRAL1 (HGNC:24987): (NmrA like redox sensor 1) This gene encodes an NADPH sensor protein that preferentially binds to NADPH. The encoded protein also negatively regulates the activity of NF-kappaB in a ubiquitylation-dependent manner. It plays a key role in cellular antiviral response by negatively regulating the interferon response factor 3-mediated expression of interferon beta. Alternative splicing of this gene results in multiple transcript variants. [provided by RefSeq, Feb 2015]

The c.819G>C (p.E273D) alteration is located in exon 6 (coding exon 5) of the NMRAL1 gene. This alteration results from a G to C substitution at nucleotide position 819, causing the glutamic acid (E) at amino acid position 273 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
