GeneDx RCV000195596 SCV000252147 uncertain significance not provided 2012-09-24 criteria provided, single submitter clinical testing p.Arg46Trp (CGG>TGG):c.136 C>T in exon 2 of the PUS1 gene (NM_025215.5) A variant of unknown significance has been identified in the PUS1 gene. The R46W missense substitution has not been published as a mutation, nor has it been reported as a benign polymorphism to our knowledge. The amino acid change is non-conservative in that a positively charged Arginine residue is replaced by an uncharged Tryptophan residue. This change occurs at a position in the PUS1 protein that is not highly conserved. In-silico analyses are not consistent in their predictions of whether or not R46W is damaging to the PUS1 protein. Therefore, based on the currently available information it is unclear whether R46W is a disease causing mutation or a rare benign variant. The variant is found in MITONUC-MITOP panel(s).
