Genes affected

RAB11FIP4 (HGNC:30267): (RAB11 family interacting protein 4) The protein encoded by this gene interacts with RAB11 and is thought to be involved in bringing recycling endosome membranes to the cleavage furrow in late cytokinesis. Hypoxic conditions can lead to an upregulation of the encoded protein and enhance the metastatic potential of hepatocellular carcinoma. [provided by RefSeq, Oct 2016]

ACMG classification

Verdict is Uncertain_significance. Variant got 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.16659442).

The c.93C>G (p.D31E) alteration is located in exon 1 (coding exon 1) of the RAB11FIP4 gene. This alteration results from a C to G substitution at nucleotide position 93, causing the aspartic acid (D) at amino acid position 31 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
