Labcorp Genetics (formerly Invitae), Labcorp RCV001873094 SCV002140560 pathogenic Jeune thoracic dystrophy; Nephronophthisis 2022-07-12 criteria provided, single submitter clinical testing This sequence change creates a premature translational stop signal (p.Ala1049Leufs*15) in the TTC21B gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in TTC21B are known to be pathogenic (PMID: 18327258, 21068128, 21258341, 23559409, 24876116, 25492405, 27491411, 29068549). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with TTC21B-related conditions. ClinVar contains an entry for this variant (Variation ID: 1372589). For these reasons, this variant has been classified as Pathogenic.
