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]

Collection Method: clinical testing

The c.19A>G (p.S7G) alteration is located in exon 1 (coding exon 1) of the YKT6 gene. This alteration results from a A to G substitution at nucleotide position 19, causing the serine (S) at amino acid position 7 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
