Genes affected

RFFL (HGNC:24821): (ring finger and FYVE like domain containing E3 ubiquitin protein ligase) Enables enzyme binding activity; p53 binding activity; and ubiquitin protein ligase activity. Involved in cellular protein metabolic process; negative regulation of cysteine-type endopeptidase activity involved in execution phase of apoptosis; and negative regulation of signal transduction. Located in endosome membrane and plasma membrane. [provided by Alliance of Genome Resources, Apr 2022]

Ambry Genetics

Feb 03, 2022

The c.766C>T (p.R256W) alteration is located in exon 5 (coding exon 4) of the RFFL gene. This alteration results from a C to T substitution at nucleotide position 766, causing the arginine (R) at amino acid position 256 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
