Genes affected

COPB1 (HGNC:2231): (COPI coat complex subunit beta 1) This gene encodes a protein subunit of the coatomer complex associated with non-clathrin coated vesicles. The coatomer complex, also known as the coat protein complex 1, forms in the cytoplasm and is recruited to the Golgi by activated guanosine triphosphatases. Once at the Golgi membrane, the coatomer complex may assist in the movement of protein and lipid components back to the endoplasmic reticulum. Alternatively spliced transcript variants have been described. [provided by RefSeq, Jan 2009]

The c.1699C>T (p.R567C) alteration is located in exon 14 (coding exon 13) of the COPB1 gene. This alteration results from a C to T substitution at nucleotide position 1699, causing the arginine (R) at amino acid position 567 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
