Invitae RCV003010082 SCV003313790 uncertain significance Holoprosencephaly 11 2022-06-25 criteria provided, single submitter clinical testing This variant is not present in population databases (gnomAD no frequency). This sequence change affects an acceptor splice site in intron 18 of the CDON gene. It is expected to disrupt RNA splicing. Variants that disrupt the donor or acceptor splice site typically lead to a loss of protein function (PMID: 16199547), however the current clinical and genetic evidence is not sufficient to establish whether loss-of-function variants in CDON cause disease. This variant has not been reported in the literature in individuals affected with CDON-related conditions. 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. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site.
