Genes affected
RAB25 (HGNC:18238): (RAB25, member RAS oncogene family) The protein encoded by this gene is a member of the RAS superfamily of small GTPases. The encoded protein is involved in membrane trafficking and cell survival. This gene has been found to be a tumor suppressor and an oncogene, depending on the context. Two variants, one protein-coding and the other not, have been found for this gene. [provided by RefSeq, Nov 2015]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 30, 2024The c.133A>T (p.I45F) alteration is located in exon 2 (coding exon 2) of the RAB25 gene. This alteration results from a A to T substitution at nucleotide position 133, causing the isoleucine (I) at amino acid position 45 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
