Genes affected
RAB26 (HGNC:14259): (RAB26, member RAS oncogene family) Members of the RAB protein family, including RAB26, are important regulators of vesicular fusion and trafficking. The RAB family of small G proteins regulates intercellular vesicle trafficking, including exocytosis, endocytosis, and recycling (summary by Seki et al., 2000 [PubMed 11043516]).[supplied by OMIM, Nov 2010]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 28, 2023The c.203T>C (p.L68P) alteration is located in exon 2 (coding exon 2) of the RAB26 gene. This alteration results from a T to C substitution at nucleotide position 203, causing the leucine (L) at amino acid position 68 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
