Genes affected

UPF2 (HGNC:17854): (UPF2 regulator of nonsense mediated mRNA decay) This gene encodes a protein that is part of a post-splicing multiprotein complex involved in both mRNA nuclear export and mRNA surveillance. mRNA surveillance detects exported mRNAs with truncated open reading frames and initiates nonsense-mediated mRNA decay (NMD). When translation ends upstream from the last exon-exon junction, this triggers NMD to degrade mRNAs containing premature stop codons. This protein is located in the perinuclear area. It interacts with translation release factors and the proteins that are functional homologs of yeast Upf1p and Upf3p. Two splice variants have been found for this gene; both variants encode the same protein. [provided by RefSeq, Jul 2008]

The c.3224A>T (p.N1075I) alteration is located in exon 17 (coding exon 16) of the UPF2 gene. This alteration results from a A to T substitution at nucleotide position 3224, causing the asparagine (N) at amino acid position 1075 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
