Genes affected

RFPL1 (HGNC:9977): (ret finger protein like 1) Predicted to enable ubiquitin-protein transferase activity. Involved in several processes, including negative regulation of G2/M transition of mitotic cell cycle; negative regulation of cell division; and positive regulation of proteolysis. Located in cytoplasm. [provided by Alliance of Genome Resources, Apr 2022]

The c.863C>T (p.P288L) alteration is located in exon 2 (coding exon 2) of the RFPL1 gene. This alteration results from a C to T substitution at nucleotide position 863, causing the proline (P) at amino acid position 288 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
