Neuberg Centre For Genomic Medicine, NCGM RCV004821440 SCV005442668 uncertain significance Rheumatoid arthritis criteria provided, single submitter clinical testing The observed frameshift variant c.841delp.Leu281TrpfsTer7 in the PTPN22 gene has not been reported previously as a pathogenic variant nor as a benign variant, to our knowledge. This variant is reported with the allele frequency 0.002% in the gnomAD Exomes. This variant causes a frameshift starting with codon Leucine 281, changes this amino acid to Tryptophan residue, and creates a premature Stop codon at position 7 of the new reading frame, denoted p.Leu281TrpfsTer7. This variant is predicted to cause loss of normal protein function through protein truncation. However, loss of function variants have not been previously reported to be disease causing. For these reasons, this variant has been classified as Uncertain Significance. The same variant has been detected in heterozygous state in sibling.
