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.

Ambry Genetics

Jun 23, 2023

The c.2102T>C (p.M701T) alteration is located in exon 15 (coding exon 15) of the NOP14 gene. This alteration results from a T to C substitution at nucleotide position 2102, causing the methionine (M) at amino acid position 701 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
