Genes affected

CALCOCO2 (HGNC:29912): (calcium binding and coiled-coil domain 2) This gene encodes a coiled-coil domain-containing protein. The encoded protein functions as a receptor for ubiquitin-coated bacteria and plays an important role in innate immunity by mediating macroautophagy. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, May 2012]

Collection Method: clinical testing

The c.649C>G (p.Q217E) alteration is located in exon 7 (coding exon 6) of the CALCOCO2 gene. This alteration results from a C to G substitution at nucleotide position 649, causing the glutamine (Q) at amino acid position 217 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
