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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 05, 2024The c.407C>T (p.A136V) alteration is located in exon 5 (coding exon 5) of the YKT6 gene. This alteration results from a C to T substitution at nucleotide position 407, causing the alanine (A) at amino acid position 136 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
