Ambry Genetics RCV004559343 SCV005047797 likely pathogenic Hereditary cancer-predisposing syndrome; Cardiovascular phenotype 2023-11-27 criteria provided, single submitter clinical testing The c.3974+260T>G intronic variant results from a T to G substitution 260 nucleotides after coding exon 29 in the NF1 gene. This alteration has been reported in a child with a clinical or genetic diagnosis of neurofibromatosis type 1 (Duat Rodríguez A et al. An Pediatr (Barc), 2015 Sep;83:173-82). This nucleotide position is conserved on limited sequence alignment. In silico splice site analysis predicts that this alteration will result in the creation or strengthening of a novel splice donor site. RNA studies have demonstrated that this alteration results in multiple abnormal transcripts (Duat Rodríguez A et al. An Pediatr (Barc), 2015 Sep;83:173-82; Ambry internal data). This variant is considered to be rare based on population cohorts in the Genome Aggregation Database (gnomAD). Based on the majority of available evidence to date, this variant is likely to be pathogenic.
