Genes affected

YKT6 (HGNC:16959): (YKT6 v-SNARE homolog) This gene product is one of the SNARE recognition molecules implicated in vesicular transport between secretory compartments. It is a membrane associated, isoprenylated protein that functions at the endoplasmic reticulum-Golgi transport step. This protein is highly conserved from yeast to human and can functionally complement the loss of the yeast homolog in the yeast secretory pathway. [provided by RefSeq, Jul 2008]

Ambry Genetics

Sep 28, 2021

The c.191A>G (p.Y64C) alteration is located in exon 3 (coding exon 3) of the YKT6 gene. This alteration results from a A to G substitution at nucleotide position 191, causing the tyrosine (Y) at amino acid position 64 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
