Labcorp Genetics (formerly Invitae), Labcorp RCV001906832 SCV002183029 pathogenic Fanconi anemia 2020-12-05 criteria provided, single submitter clinical testing For these reasons, this variant has been classified as Pathogenic. Retrotransposon insertions including LINE1 (L1), Alu, and SVA (SINE-VNTR-Alu) have been reported to be disease-causing through disruption of either a coding region or splice site (PMID: 19763152, 20307669, 22406018) and loss-of-function variants in FANCA are known to be pathogenic (PMID: 19367192). This variant has not been reported in the literature in individuals with FANCA-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change inserts a large fragment of DNA, likely a transposable element, in exon 31 of the FANCA gene (c.3019_3020ins?), causing a frameshift at codon 1007 (p.Val1007fs). The exact size and sequence of the insertion cannot be determined by the current assay. However, the insertion is expected to result in an absent or disrupted protein product.
