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.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 21, 2023The c.779A>G (p.Y260C) alteration is located in exon 10 (coding exon 10) of the SEC14L3 gene. This alteration results from a A to G substitution at nucleotide position 779, causing the tyrosine (Y) at amino acid position 260 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
