Genes affected

NBR1 (HGNC:6746): (NBR1 autophagy cargo receptor) The protein encoded by this gene was originally identified as an ovarian tumor antigen monitored in ovarian cancer. The encoded protein contains a B-box/coiled-coil motif, which is present in many genes with transformation potential. It functions as a specific autophagy receptor for the selective autophagic degradation of peroxisomes by forming intracellular inclusions with ubiquitylated autophagic substrates. This gene is located on a region of chromosome 17q21.1 that is in close proximity to the BRCA1 tumor suppressor gene. Alternative splicing of this gene results in multiple transcript variants.

The c.676G>C (p.G226R) alteration is located in exon 8 (coding exon 7) of the NBR1 gene. This alteration results from a G to C substitution at nucleotide position 676, causing the glycine (G) at amino acid position 226 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
