Genes affected
UCN2 (HGNC:18414): (urocortin 2) This gene is a member of the sauvagine/corticotropin-releasing factor/urotensin I family. It is structurally related to the corticotropin-releasing factor (CRF) gene and the encoded product is an endogenous ligand for CRF type 2 receptors. In the brain it may be responsible for the effects of stress on appetite. In spite of the gene family name similarity, the product of this gene has no sequence similarity to urotensin II.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 08, 2023The c.306C>A (p.N102K) alteration is located in exon 2 (coding exon 1) of the UCN2 gene. This alteration results from a C to A substitution at nucleotide position 306, causing the asparagine (N) at amino acid position 102 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
