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 GeneticsNov 15, 2021The c.703G>A (p.A235T) alteration is located in exon 5 (coding exon 5) of the PM20D1 gene. This alteration results from a G to A substitution at nucleotide position 703, causing the alanine (A) at amino acid position 235 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
