Genes affected

NOL7 (HGNC:21040): (nucleolar protein 7) The protein encoded by this gene localizes to the nucleolus, where it maintains nucleolar structure and cell growth rates. The encoded protein also functions as a tumor suppressor and regulator of angiogenesis. The RB tumor suppressor gene recruits transcription factors to this gene and positively regulates its expression. Two transcript variants encoding the same protein have been found for this gene.

The c.737G>A (p.R246K) alteration is located in exon 8 (coding exon 8) of the NOL7 gene. This alteration results from a G to A substitution at nucleotide position 737, causing the arginine (R) at amino acid position 246 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
