Genes affected

CALU (HGNC:1458): (calumenin) The product of this gene is a calcium-binding protein localized in the endoplasmic reticulum (ER) and it is involved in such ER functions as protein folding and sorting. This protein belongs to a family of multiple EF-hand proteins (CERC) that include reticulocalbin, ERC-55, and Cab45 and the product of this gene. Alternatively spliced transcript variants encoding different isoforms have been identified. [provided by RefSeq, Oct 2008]

Collection Method: clinical testing

The c.271G>A (p.D91N) alteration is located in exon 4 (coding exon 3) of the CALU gene. This alteration results from a G to A substitution at nucleotide position 271, causing the aspartic acid (D) at amino acid position 91 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
