Genes affected

GNL3 (HGNC:29931): (G protein nucleolar 3) The protein encoded by this gene may interact with p53 and may be involved in tumorigenesis. The encoded protein also appears to be important for stem cell proliferation. This protein is found in both the nucleus and nucleolus. Three transcript variants encoding two different isoforms have been found for this gene. [provided by RefSeq, Nov 2010]

Feb 16, 2023

The c.527T>A (p.I176K) alteration is located in exon 6 (coding exon 6) of the GNL3 gene. This alteration results from a T to A substitution at nucleotide position 527, causing the isoleucine (I) at amino acid position 176 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
