Genes affected

COPZ1 (HGNC:2243): (COPI coat complex subunit zeta 1) This gene encodes a subunit of the cytoplasmic coatamer protein complex, which is involved in autophagy and intracellular protein trafficking. The coatomer protein complex is comprised of seven subunits and functions as the coat protein of coat protein complex (COP)I-vesicles. Alternative splicing results in multiple transcript variants.

The c.280C>A (p.L94M) alteration is located in exon 5 (coding exon 5) of the COPZ1 gene. This alteration results from a C to A substitution at nucleotide position 280, causing the leucine (L) at amino acid position 94 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
