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

Apr 04, 2024

The c.116C>T (p.P39L) alteration is located in exon 2 (coding exon 1) of the POLR3G gene. This alteration results from a C to T substitution at nucleotide position 116, causing the proline (P) at amino acid position 39 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
