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]

The c.350G>A (p.R117Q) alteration is located in exon 4 (coding exon 3) of the CALCOCO2 gene. This alteration results from a G to A substitution at nucleotide position 350, causing the arginine (R) at amino acid position 117 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
