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.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 08, 2023The c.560A>G (p.K187R) alteration is located in exon 7 (coding exon 5) of the PCIF1 gene. This alteration results from a A to G substitution at nucleotide position 560, causing the lysine (K) at amino acid position 187 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
