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]

Ambry Genetics

Dec 28, 2022

The c.1453C>T (p.L485F) alteration is located in exon 13 (coding exon 12) of the RPAP3 gene. This alteration results from a C to T substitution at nucleotide position 1453, causing the leucine (L) at amino acid position 485 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
