Genes affected
RAB31 (HGNC:9771): (RAB31, member RAS oncogene family) Enables GDP binding activity and GTP binding activity. Involved in several processes, including Golgi to plasma membrane protein transport; cellular response to insulin stimulus; and receptor internalization. Located in early endosome; phagocytic vesicle; and trans-Golgi network membrane. Biomarker of severe acute respiratory syndrome. [provided by Alliance of Genome Resources, Apr 2022]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 29, 2023The c.101A>G (p.N34S) alteration is located in exon 2 (coding exon 2) of the RAB31 gene. This alteration results from a A to G substitution at nucleotide position 101, causing the asparagine (N) at amino acid position 34 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
