Genes affected

NUCB1 (HGNC:8043): (nucleobindin 1) This gene encodes a member of a small calcium-binding EF-hand protein family. The encoded protein is thought to have a key role in Golgi calcium homeostasis and Ca(2+)-regulated signal transduction events. [provided by RefSeq, Jun 2010]

The c.94G>C (p.G32R) alteration is located in exon 2 (coding exon 1) of the NUCB1 gene. This alteration results from a G to C substitution at nucleotide position 94, causing the glycine (G) at amino acid position 32 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
