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 GeneticsSep 14, 2022The c.734T>C (p.L245P) alteration is located in exon 7 (coding exon 6) of the POLR3D gene. This alteration results from a T to C substitution at nucleotide position 734, causing the leucine (L) at amino acid position 245 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
