Genes affected

NOP16 (HGNC:26934): (NOP16 nucleolar protein) This gene encodes a protein that is localized to the nucleolus. Expression of this gene is induced by estrogens and Myc protein and is a marker of poor patient survival in breast cancer. Alternative splicing results in multiple transcript variants.

ARL10 (HGNC:22042): (ADP ribosylation factor like GTPase 10) Predicted to enable GTP binding activity and GTPase activity. [provided by Alliance of Genome Resources, Apr 2022]

The c.445C>T (p.R149W) alteration is located in exon 5 (coding exon 5) of the NOP16 gene. This alteration results from a C to T substitution at nucleotide position 445, causing the arginine (R) at amino acid position 149 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
