Genes affected

SEC14L3 (HGNC:18655): (SEC14 like lipid binding 3) The protein encoded by this gene is highly similar to the protein encoded by the Saccharomyces cerevisiae SEC14 gene. The SEC14 protein is a phophatidylinositol transfer protein that is essential for biogenesis of Golgi-derived transport vesicles, and thus is required for the export of yeast secretory proteins from the Golgi complex. The specific function of this protein has not yet been determined. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene.

The c.940A>G (p.I314V) alteration is located in exon 11 (coding exon 11) of the SEC14L3 gene. This alteration results from a A to G substitution at nucleotide position 940, causing the isoleucine (I) at amino acid position 314 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
