Genes affected

NOP14 (HGNC:16821): (NOP14 nucleolar protein) This gene encodes a protein that plays a role in pre-18s rRNA processing and small ribosomal subunit assembly. The encoded protein may be involved in the regulation of pancreatic cancer cell proliferation and migration. Alternative splicing results in multiple transcript variants.

The c.2268G>C (p.E756D) alteration is located in exon 16 (coding exon 16) of the NOP14 gene. This alteration results from a G to C substitution at nucleotide position 2268, causing the glutamic acid (E) at amino acid position 756 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
