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.

The 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. -
