Genes affected

CANX (HGNC:1473): (calnexin) This gene encodes a member of the calnexin family of molecular chaperones. The encoded protein is a calcium-binding, endoplasmic reticulum (ER)-associated protein that interacts transiently with newly synthesized N-linked glycoproteins, facilitating protein folding and assembly. It may also play a central role in the quality control of protein folding by retaining incorrectly folded protein subunits within the ER for degradation. Alternatively spliced transcript variants encoding different isoforms have been described. [provided by RefSeq, Jun 2018]

The c.425A>G (p.D142G) alteration is located in exon 5 (coding exon 4) of the CANX gene. This alteration results from a A to G substitution at nucleotide position 425, causing the aspartic acid (D) at amino acid position 142 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
