Invitae RCV000228085 SCV000288359 uncertain significance Neuroblastoma 3 2019-12-04 criteria provided, single submitter clinical testing This sequence change affects codon 1425 of the ALK mRNA. It is a 'silent' change, meaning that it does not change the encoded amino acid sequence of the ALK protein. This variant is present in population databases (rs749418931, ExAC 0.02%). This variant has not been reported in the literature in individuals with ALK-related disease. ClinVar contains an entry for this variant (Variation ID: 239835). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site, but this prediction has not been confirmed by published transcriptional studies. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance.
Illumina Clinical Services Laboratory,Illumina RCV000228085 SCV001304103 likely benign Neuroblastoma 3 2018-01-13 criteria provided, single submitter clinical testing This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score and internal cut-off values, a variant classified as likely benign is not then subjected to further curation. The score for this variant resulted in a classification of likely benign for this disease.
