Ambry Genetics RCV004523226 SCV005034298 uncertain significance Hereditary cancer-predisposing syndrome 2023-10-26 criteria provided, single submitter clinical testing The c.831_832insAlu variant results from the insertion of an Alu element between nucleotides 831 and 832 in coding exon 9 of the NF2 gene. Mobile element insertions contribute to pathogenicity by either disrupting the coding sequence or inducing aberrant splicing (Belancio VP et al. Semin. Cancer Biol. 2010 Aug;20:200-10; Deininger P et al. Genome Biol. 2011 Dec;12:236; van der Klift HM Hum Mutat. 2012 Jul;33(7):1051-5). One possible aberrant splice effect would be in-frame and, therefore, not expected to trigger nonsense-mediated mRNAdecay; however, direct evidence is unavailable. The exact functional effect of the altered amino acid sequence is unknown. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
