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. [provided by Alliance of Genome Resources, Apr 2022]
PM20D1-AS1 (HGNC:27633): (PM20D1 antisense RNA 1)

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 06, 2023The c.1049A>G (p.N350S) alteration is located in exon 10 (coding exon 10) of the PM20D1 gene. This alteration results from a A to G substitution at nucleotide position 1049, causing the asparagine (N) at amino acid position 350 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
