Genes affected

PUS3 (HGNC:25461): (pseudouridine synthase 3) The protein encoded by this gene catalyzes the formation of tRNA pseudouridine from tRNA uridine at position 39 in the anticodon stem and loop of transfer RNAs. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Dec 2012]

PUS3 links:

HYLS1 (HGNC:26558): (HYLS1 centriolar and ciliogenesis associated) This gene encodes a protein localized to the cytoplasm. Mutations in this gene are associated with hydrolethalus syndrome. Multiple alternatively spliced variants, encoding the same protein, have been identified. [provided by RefSeq, Oct 2008]

The c.1361A>G (p.N454S) alteration is located in exon 4 (coding exon 3) of the PUS3 gene. This alteration results from a A to G substitution at nucleotide position 1361, causing the asparagine (N) at amino acid position 454 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

This sequence change replaces asparagine, which is neutral and polar, with serine, which is neutral and polar, at codon 454 of the PUS3 protein (p.Asn454Ser). This variant is present in population databases (rs201997946, gnomAD 0.08%). This variant has not been reported in the literature in individuals affected with PUS3-related conditions. ClinVar contains an entry for this variant (Variation ID: 1442454). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The serine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
