Labcorp Genetics (formerly Invitae), Labcorp RCV001990206 SCV002234121 uncertain significance Jeune thoracic dystrophy; Nephronophthisis 2021-06-19 criteria provided, single submitter clinical testing This variant results in a copy number gain of the genomic region encompassing exon(s) 1-24 of the TTC21B gene. This region includes the initiator codon of the gene. The 5' end of this event is unknown as it extends beyond the assayed region for this gene and therefore may encompass additional genes. The 3' boundary is likely confined to intron 24 of the TTC21B gene. As the precise location of this event is unknown, it may be in tandem or it may be located elsewhere in the genome. This variant has not been reported in the literature in individuals with TTC21B-related conditions. Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. 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.
