Labcorp Genetics (formerly Invitae), Labcorp	RCV000527368	SCV000659424	uncertain significance	Adams-Oliver syndrome 5	2024-08-04	criteria provided, single submitter	clinical testing	This sequence change falls in intron 21 of the NOTCH1 gene. It does not directly change the encoded amino acid sequence of the NOTCH1 protein. It affects a nucleotide within the consensus splice site. The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This variant has not been reported in the literature in individuals affected with NOTCH1-related conditions. ClinVar contains an entry for this variant (Variation ID: 477915). Variants that disrupt the consensus splice site are a relatively common cause of aberrant splicing (PMID: 17576681, 9536098). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant is not likely to affect RNA splicing. 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.

Ambry Genetics	RCV003343924	SCV004074152	uncertain significance	Familial thoracic aortic aneurysm and aortic dissection	2023-08-14	criteria provided, single submitter	clinical testing	The c.3510+3G>A intronic variant results from a G to A substitution 3 nucleotides after coding exon 21 in the NOTCH1 gene. This nucleotide position is not well conserved in available vertebrate species. In silico splice site analysis predicts that this alteration will not have any significant effect on splicing. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
