Genes affected
POLR3D (HGNC:1080): (RNA polymerase III subunit D) This gene complements a temperature-sensitive mutant isolated from the BHK-21 Syrian hamster cell line. It leads to a block in progression through the G1 phase of the cell cycle at nonpermissive temperatures. [provided by RefSeq, Jul 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 20, 2021The c.466C>T (p.R156C) alteration is located in exon 5 (coding exon 4) of the POLR3D gene. This alteration results from a C to T substitution at nucleotide position 466, causing the arginine (R) at amino acid position 156 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
