Breakpoint-level characterization of a novel CEP290 tandem duplication in trans with a pathogenic splice-site variant in a patient with Leber congenital amaurosis.
This study represents the first breakpoint-resolved characterization of a pathogenic CEP290 tandem duplication encompassing exons 31-53 identified in compound heterozygosity with a pathogenic splice-site variant in a patient with early-onset retinal degeneration.
