Genes affected

LNPEP (HGNC:6656): (leucyl and cystinyl aminopeptidase) This gene encodes a zinc-dependent aminopeptidase that cleaves vasopressin, oxytocin, lys-bradykinin, met-enkephalin, dynorphin A and other peptide hormones. The protein can be secreted in maternal serum, reside in intracellular vesicles with the insulin-responsive glucose transporter GLUT4, or form a type II integral membrane glycoprotein. The protein catalyzes the final step in the conversion of angiotensinogen to angiotensin IV (AT4) and is also a receptor for AT4. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Jul 2008]

Nov 03, 2022

The c.434A>C (p.N145T) alteration is located in exon 2 (coding exon 2) of the LNPEP gene. This alteration results from a A to C substitution at nucleotide position 434, causing the asparagine (N) at amino acid position 145 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
