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]

Ambry Genetics

Jan 25, 2023

The c.301G>T (p.D101Y) alteration is located in exon 4 (coding exon 3) of the NUCB1 gene. This alteration results from a G to T substitution at nucleotide position 301, causing the aspartic acid (D) at amino acid position 101 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
