Genes affected
QPCT (HGNC:9753): (glutaminyl-peptide cyclotransferase) This gene encodes human pituitary glutaminyl cyclase, which is responsible for the presence of pyroglutamyl residues in many neuroendocrine peptides. The amino acid sequence of this enzyme is 86% identical to that of bovine glutaminyl cyclase. [provided by RefSeq, Jul 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 01, 2024The c.689C>G (p.P230R) alteration is located in exon 4 (coding exon 4) of the QPCT gene. This alteration results from a C to G substitution at nucleotide position 689, causing the proline (P) at amino acid position 230 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
