Genes affected

RAB12 (HGNC:31332): (RAB12, member RAS oncogene family) Enables GDP binding activity. Predicted to be involved in several processes, including cellular response to insulin stimulus; endosome to lysosome transport; and secretion by cell. Predicted to act upstream of or within cellular response to interferon-gamma. Predicted to be located in lysosome; phagocytic vesicle; and recycling endosome membrane. Predicted to be active in Golgi apparatus; cytoplasmic vesicle; and plasma membrane. [provided by Alliance of Genome Resources, Apr 2022]

The c.656A>G (p.N219S) alteration is located in exon 6 (coding exon 6) of the RAB12 gene. This alteration results from a A to G substitution at nucleotide position 656, causing the asparagine (N) at amino acid position 219 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
