Genes affected
PTRHD1 (HGNC:33782): (peptidyl-tRNA hydrolase domain containing 1) This gene encodes the enzyme peptidyl-tRNA hydrolase. Peptidyl-tRNA hydrolases perform the essential function of recycling peptidyl-tRNAs. Mutations in this gene are associated with autosomal-recessive intellectual disability and parkinsonism.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 13, 2022The c.301A>G (p.K101E) alteration is located in exon 2 (coding exon 2) of the PTRHD1 gene. This alteration results from a A to G substitution at nucleotide position 301, causing the lysine (K) at amino acid position 101 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

PTRHD1-related disorder Uncertain:1
Uncertain significance, no assertion criteria providedclinical testingPreventionGenetics, part of Exact SciencesAug 12, 2024The PTRHD1 c.301A>G variant is predicted to result in the amino acid substitution p.Lys101Glu. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.051% of alleles in individuals of European (Non-Finnish) descent in gnomAD. Although we suspect that this variant may be benign, at this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
