Labcorp Genetics (formerly Invitae), Labcorp RCV001203301 SCV001374458 uncertain significance Multiple congenital exostosis 2019-09-26 criteria provided, single submitter clinical testing 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. Nucleotide substitutions within 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 may disrupt the consensus splice site, but this prediction has not been confirmed by published transcriptional studies. This variant has been observed in an individual affected with multiple osteochondromas (Invitae). This variant is not present in population databases (ExAC no frequency). This sequence change falls in intron 3 of the EXT1 gene. It does not directly change the encoded amino acid sequence of the EXT1 protein, but it affects a nucleotide within the consensus splice site of the intron.
