Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the TYW1 gene is commonly pathogenic or not. These statistics are base on transcript: NM_000018264.4. Only rare variants are included in the table.

In the table, we include only reliable ClinVar variants with their consequences to MANE Select, Mane Plus Clinical transcripts, or transcripts with TSL equals 1. Click the count to view the source variants.

Warning: slight differences between displayed counts and the number of variants in ClinVar may occur, primarily due to (1) the application of a different transcript and/or consequence by our variant effect predictor or (2) differences in clinical significance: we classify Benign/Likely benign variants as Likely benign and Pathogenic/Likely pathogenic variants as Likely pathogenic.

• Function: FUNCTION: Probable component of the wybutosine biosynthesis pathway. Wybutosine is a hyper modified guanosine with a tricyclic base found at the 3'-position adjacent to the anticodon of eukaryotic phenylalanine tRNA. Catalyzes the condensation of N- methylguanine with 2 carbon atoms from pyruvate to form the tricyclic 4-demethylwyosine, an intermediate in wybutosine biosynthesis (By similarity). {ECO:0000250}.
• Pathway: Synthesis of wybutosine at G37 of tRNA(Phe);tRNA modification in the nucleus and cytosol;tRNA processing;Metabolism of RNA;wybutosine biosynthesis;7-(3-amino-3-carboxypropyl)-wyosine biosynthesis (Consensus)
