Genes affected

VPS54 (HGNC:18652): (VPS54 subunit of GARP complex) This gene encodes for a protein that in yeast forms part of a trimeric vacuolar-protein-sorting complex that is required for retrograde transport of proteins from prevacuoles to the late Golgi compartment. As in yeast, mammalian Vps54 proteins contain a coiled-coil region and dileucine motifs. Alternative splicing results in multiple transcript variants encoding different isoforms [provided by RefSeq, Jul 2008]

The c.1847A>G (p.K616R) alteration is located in exon 13 (coding exon 12) of the VPS54 gene. This alteration results from a A to G substitution at nucleotide position 1847, causing the lysine (K) at amino acid position 616 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
