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.1956C>G (p.I652M) alteration is located in exon 14 (coding exon 13) of the VPS54 gene. This alteration results from a C to G substitution at nucleotide position 1956, causing the isoleucine (I) at amino acid position 652 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
