Genes affected
PNMT (HGNC:9160): (phenylethanolamine N-methyltransferase) The product of this gene catalyzes the last step of the catecholamine biosynthesis pathway, which methylates norepinephrine to form epinephrine (adrenaline). The enzyme also has beta-carboline 2N-methyltransferase activity. This gene is thought to play a key step in regulating epinephrine production. Alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Nov 2012]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 15, 2022The c.134G>C (p.G45A) alteration is located in exon 1 (coding exon 1) of the PNMT gene. This alteration results from a G to C substitution at nucleotide position 134, causing the glycine (G) at amino acid position 45 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
