Invitae RCV001089797 SCV001245291 pathogenic Fanconi anemia 2019-07-13 criteria provided, single submitter clinical testing This sequence change inserts a large fragment of DNA, likely a transposable element, in exon 15 of the FANCM gene (c.4304_4305insSVA), causing a frameshift at codon 1435 (p.Leu1435fs). 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. This variant has not been reported in the literature in individuals with FANCM-related conditions. 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 FANCM are known to be pathogenic (PMID: 29895858, 30075111). For these reasons, this variant has been classified as Pathogenic.
