Genes affected

RAB11FIP3 (HGNC:17224): (RAB11 family interacting protein 3) Proteins of the large Rab GTPase family (see RAB1A; MIM 179508) have regulatory roles in the formation, targeting, and fusion of intracellular transport vesicles. RAB11FIP3 is one of many proteins that interact with and regulate Rab GTPases (Hales et al., 2001 [PubMed 11495908]).[supplied by OMIM, Mar 2008]

ACMG classification

Verdict is Likely_benign. Variant got -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.054976135).

The c.19G>C (p.A7P) alteration is located in exon 1 (coding exon 1) of the RAB11FIP3 gene. This alteration results from a G to C substitution at nucleotide position 19, causing the alanine (A) at amino acid position 7 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
