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 GeneticsJul 27, 2022The c.155G>A (p.R52H) alteration is located in exon 2 (coding exon 2) of the RAB25 gene. This alteration results from a G to A substitution at nucleotide position 155, causing the arginine (R) at amino acid position 52 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
