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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 18, 2024The c.499A>G (p.I167V) alteration is located in exon 2 (coding exon 2) of the RFPL1 gene. This alteration results from a A to G substitution at nucleotide position 499, causing the isoleucine (I) at amino acid position 167 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
