Genes affected
DTD1 (HGNC:16219): (D-aminoacyl-tRNA deacylase 1) The protein encoded by this gene is similar in sequence to histidyl-tRNA synthetase, which hydrolyzes D-tyrosyl-tRNA(Tyr) into D-tyrosine and free tRNA(Tyr). The encoded protein binds the DNA unwinding element and plays a role in the initiation of DNA replication. Alternative splicing results in multiple transcript variants encoding different isoforms.

Submissions by phenotype
not specified Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | May 17, 2023 | The c.278T>G (p.F93C) alteration is located in exon 3 (coding exon 3) of the DTD1 gene. This alteration results from a T to G substitution at nucleotide position 278, causing the phenylalanine (F) at amino acid position 93 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
