Genes affected

COPE (HGNC:2234): (COPI coat complex subunit epsilon) The product of this gene is an epsilon subunit of coatomer protein complex. Coatomer is a cytosolic protein complex that binds to dilysine motifs and reversibly associates with Golgi non-clathrin-coated vesicles. It is required for budding from Golgi membranes, and is essential for the retrograde Golgi-to-ER transport of dilysine-tagged proteins. Coatomer complex consists of at least the alpha, beta, beta', gamma, delta, epsilon and zeta subunits. Alternatively spliced transcript variants encoding different isoforms have been identified.

The c.340G>T (p.V114L) alteration is located in exon 4 (coding exon 4) of the COPE gene. This alteration results from a G to T substitution at nucleotide position 340, causing the valine (V) at amino acid position 114 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
