Genes affected

VPS18 (HGNC:15972): (VPS18 core subunit of CORVET and HOPS complexes) Vesicle mediated protein sorting plays an important role in segregation of intracellular molecules into distinct organelles. Genetic studies in yeast have identified more than 40 vacuolar protein sorting (VPS) genes involved in vesicle transport to vacuoles. This gene encodes the human homolog of yeast class C Vps18 protein. The mammalian class C Vps proteins are predominantly associated with late endosomes/lysosomes, and like their yeast counterparts, may mediate vesicle trafficking steps in the endosome/lysosome pathway.

The c.464G>A (p.S155N) alteration is located in exon 4 (coding exon 4) of the VPS18 gene. This alteration results from a G to A substitution at nucleotide position 464, causing the serine (S) at amino acid position 155 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
