Genes affected

POLR3G (HGNC:30075): (RNA polymerase III subunit G) Enables chromatin binding activity. Involved in positive regulation of innate immune response; positive regulation of interferon-beta production; and transcription by RNA polymerase III. Acts upstream of or within cell population proliferation. Located in cytosol and nuclear body. Part of RNA polymerase III complex. [provided by Alliance of Genome Resources, Apr 2022]

Ambry Genetics

Feb 23, 2023

The c.314G>T (p.R105I) alteration is located in exon 5 (coding exon 4) of the POLR3G gene. This alteration results from a G to T substitution at nucleotide position 314, causing the arginine (R) at amino acid position 105 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
