Ambry Genetics	RCV000708723	SCV000185629	likely benign	Hereditary cancer-predisposing syndrome	2023-07-13	criteria provided, single submitter	clinical testing	This alteration is classified as likely benign based on a combination of the following: population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity.

Ambry Genetics	RCV002326845	SCV001178582	likely benign	Hereditary cancer-predisposing syndrome; Cardiovascular phenotype	2019-05-08	criteria provided, single submitter	clinical testing	This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity.
Illumina Laboratory Services, Illumina	RCV001121969	SCV001280638	likely benign	Neurofibromatosis-Noonan syndrome	2018-01-12	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.
Illumina Laboratory Services, Illumina	RCV001121970	SCV001280639	uncertain significance	Neurofibromatosis, familial spinal	2018-01-12	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, this variant could not be ruled out of causing disease and therefore its association with disease required further investigation. A literature search was performed for the gene, cDNA change, and amino acid change (if applicable). No publications were found based on this search. This variant was therefore classified as a variant of unknown significance for this disease.

Lurie Children's Hospital of Chicago	RCV000765345	SCV002495858	uncertain significance	Neurofibromatosis, familial spinal; Juvenile myelomonocytic leukemia; Neurofibromatosis, type 1; Neurofibromatosis-Noonan syndrome; Café-au-lait macules with pulmonary stenosis	2021-08-11	criteria provided, single submitter	clinical testing	NF1 NM_000267.3 exon 10 p.His389Arg (c.1166A>G): This variant has been reported in the literature in at least 2 individuals: 1 individual with clinical suspicion of Neurofibromatosis-1 (NF1) and 1 individual with NF1; of note, this individual was reported to have a second, truncating NF1 variant (Warejko 2018 PMID:29483232; Kluwe 2021 PMID:33231931). This variant is present in 0.01% (10/68020) of European alleles in the Genome Aggregation Database (https://gnomad.broadinstitute.org/variant/17-31201140-A-G?dataset=gnomad_r3). This variant is present in ClinVar (Variation ID:141982). Evolutionary conservation and computational predictive tools suggest that this variant may not impact the protein. In summary, data on this variant is insufficient for disease classification. Therefore, the clinical significance of this variant is uncertain.
