Genes affected
PCSK1N (HGNC:17301): (proprotein convertase subtilisin/kexin type 1 inhibitor) The protein encoded by this gene functions as an inhibitor of prohormone convertase 1, which regulates the proteolytic cleavage of neuroendocrine peptide precursors. The proprotein is further processed into multiple short peptides. A polymorphism within this gene may be associated with obesity. [provided by RefSeq, Aug 2013]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 01, 2022The c.736G>C (p.E246Q) alteration is located in exon 3 (coding exon 3) of the PCSK1N gene. This alteration results from a G to C substitution at nucleotide position 736, causing the glutamic acid (E) at amino acid position 246 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
