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. [provided by RefSeq, May 2014]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 03, 2022The c.2491C>T (p.R831W) alteration is located in exon 18 (coding exon 18) of the NOP14 gene. This alteration results from a C to T substitution at nucleotide position 2491, causing the arginine (R) at amino acid position 831 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
