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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 12, 2024The c.428C>T (p.P143L) alteration is located in exon 5 (coding exon 4) of the NUCB1 gene. This alteration results from a C to T substitution at nucleotide position 428, causing the proline (P) at amino acid position 143 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
