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 GeneticsApr 23, 2024The c.62C>A (p.A21E) alteration is located in exon 1 (coding exon 1) of the PNMT gene. This alteration results from a C to A substitution at nucleotide position 62, causing the alanine (A) at amino acid position 21 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
