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.

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 08, 2024The c.598G>A (p.E200K) alteration is located in exon 7 (coding exon 5) of the PCIF1 gene. This alteration results from a G to A substitution at nucleotide position 598, causing the glutamic acid (E) at amino acid position 200 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
