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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 27, 2023The c.283G>T (p.A95S) alteration is located in exon 3 (coding exon 2) of the RFFL gene. This alteration results from a G to T substitution at nucleotide position 283, causing the alanine (A) at amino acid position 95 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
