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.104G>A (p.R35H) alteration is located in exon 3 (coding exon 2) of the CALU gene. This alteration results from a G to A substitution at nucleotide position 104, causing the arginine (R) at amino acid position 35 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
