Genes affected

PUS10 (HGNC:26505): (pseudouridine synthase 10) Pseudouridination, the isomerization of uridine to pseudouridine, is the most common posttranscriptional nucleotide modification found in RNA and is essential for biologic functions such as spliceosome biogenesis. Pseudouridylate synthases, such as PUS10, catalyze pseudouridination of structural RNAs, including transfer, ribosomal, and splicing RNAs. These enzymes also act as RNA chaperones, facilitating the correct folding and assembly of tRNAs (McCleverty et al., 2007 [PubMed 17900615]).[supplied by OMIM, May 2009]

The c.809A>G (p.N270S) alteration is located in exon 10 (coding exon 9) of the PUS10 gene. This alteration results from a A to G substitution at nucleotide position 809, causing the asparagine (N) at amino acid position 270 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
