Genes affected
RPAP3 (HGNC:26151): (RNA polymerase II associated protein 3) This gene encodes an RNA polymerase II-associated protein. The encoded protein may function in transcriptional regulation and may also regulate apoptosis. Alternatively spliced transcript variants have been described. [provided by RefSeq, Mar 2009]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 03, 2022The c.1276C>T (p.P426S) alteration is located in exon 12 (coding exon 11) of the RPAP3 gene. This alteration results from a C to T substitution at nucleotide position 1276, causing the proline (P) at amino acid position 426 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
