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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 16, 2024The c.4G>T (p.A2S) alteration is located in exon 2 (coding exon 1) of the POLR3G gene. This alteration results from a G to T substitution at nucleotide position 4, causing the alanine (A) at amino acid position 2 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
