Labcorp Genetics (formerly Invitae), Labcorp RCV003812278 SCV004606994 uncertain significance Drash syndrome; Frasier syndrome; Wilms tumor 1; 11p partial monosomy syndrome 2023-09-04 criteria provided, single submitter clinical testing Downstream of the non-canonical translation start site (CTG) at codon 1, the nearest methionine codon that can be used to initiate translation of the WT1 protein lies at codon 69. This downstream in-frame ATG is known as a major initiation site (PMID: 28811308, 16987884, 8621495). The functional significance of the different WT1 protein isoforms is unknown (PMID: 8621495), however mice lacking the N-terminal 68 amino acids develop normally and are fertile (PMID: 12640141). Based on these results, the impact of this variant on WT1 protein function is uncertain. 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. This variant has not been reported in the literature in individuals affected with WT1-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change creates a premature translational stop signal (p.Ala61Argfs*16) in the WT1 gene. It is unclear whether it will result in an absent or disrupted protein product because a major initiation site located at codon 69 has the potential to rescue this variant.
