Genes affected

EXOC6 (HGNC:23196): (exocyst complex component 6) The protein encoded by this gene is highly similar to the Saccharomyces cerevisiae SEC15 gene product, which is essential for vesicular traffic from the Golgi apparatus to the cell surface in yeast. It is one of the components of a multiprotein complex required for exocytosis. The 5' portion of this gene and two neighboring cytochrome p450 genes are included in a deletion that results in an autosomal-dominant form of nonsyndromic optic nerve aplasia (ONA). Alternative splicing and the use of alternative promoters results in multiple transcript variants. A paralogous gene encoding a similar protein is present on chromosome 2.

The c.337G>A (p.E113K) alteration is located in exon 4 (coding exon 4) of the EXOC6 gene. This alteration results from a G to A substitution at nucleotide position 337, causing the glutamic acid (E) at amino acid position 113 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
