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.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 21, 2024The c.1192C>A (p.P398T) alteration is located in exon 11 (coding exon 11) of the PM20D1 gene. This alteration results from a C to A substitution at nucleotide position 1192, causing the proline (P) at amino acid position 398 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
