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 submitter | clinical testing | Ambry Genetics | Nov 07, 2023 | The c.191G>T (p.S64I) alteration is located in exon 3 (coding exon 2) of the POLR3D gene. This alteration results from a G to T substitution at nucleotide position 191, causing the serine (S) at amino acid position 64 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
