Genes affected

PCIF1 (HGNC:16200): (phosphorylated CTD interacting factor 1) Enables RNA polymerase II C-terminal domain phosphoserine binding activity; S-adenosyl-L-methionine binding activity; and mRNA (2'-O-methyladenosine-N6-)-methyltransferase activity. Involved in mRNA methylation; negative regulation of translation; and positive regulation of translation. Located in intercellular bridge; microtubule cytoskeleton; and nucleoplasm.

Ambry Genetics

Dec 20, 2021

The c.24C>G (p.S8R) alteration is located in exon 3 (coding exon 1) of the PCIF1 gene. This alteration results from a C to G substitution at nucleotide position 24, causing the serine (S) at amino acid position 8 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
