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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 27, 2022The c.1268T>A (p.M423K) alteration is located in exon 12 (coding exon 12) of the GNL3 gene. This alteration results from a T to A substitution at nucleotide position 1268, causing the methionine (M) at amino acid position 423 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
