Genes affected

PM20D1 (HGNC:26518): (peptidase M20 domain containing 1) Enables hydrolase activity, acting on carbon-nitrogen (but not peptide) bonds, in linear amides. Involved in several processes, including amide biosynthetic process; cellular amide catabolic process; and negative regulation of neuron death. Located in extracellular exosome.

Ambry Genetics

Dec 21, 2023

The c.1238G>A (p.R413H) alteration is located in exon 11 (coding exon 11) of the PM20D1 gene. This alteration results from a G to A substitution at nucleotide position 1238, causing the arginine (R) at amino acid position 413 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
