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]
NUCB1-AS1 (HGNC:40419): (NUCB1 antisense RNA 1)

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 24, 2024The c.640C>T (p.R214C) alteration is located in exon 6 (coding exon 5) of the NUCB1 gene. This alteration results from a C to T substitution at nucleotide position 640, causing the arginine (R) at amino acid position 214 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
