Genes affected
CBY3 (HGNC:33278): (chibby family member 3)
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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 04, 2022The c.387C>G (p.N129K) alteration is located in exon 2 (coding exon 2) of the CBY3 gene. This alteration results from a C to G substitution at nucleotide position 387, causing the asparagine (N) at amino acid position 129 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
