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.373A>G (p.M125V) alteration is located in exon 6 (coding exon 5) of the NBR1 gene. This alteration results from a A to G substitution at nucleotide position 373, causing the methionine (M) at amino acid position 125 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
