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.

Dec 01, 2022

The c.1459C>A (p.Q487K) alteration is located in exon 13 (coding exon 13) of the PM20D1 gene. This alteration results from a C to A substitution at nucleotide position 1459, causing the glutamine (Q) at amino acid position 487 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
