Labcorp Genetics (formerly Invitae), Labcorp	RCV000707693	SCV000836800	pathogenic	Cohen syndrome	2018-02-26	criteria provided, single submitter	clinical testing	For these reasons, this variant has been classified as Pathogenic. Donor and acceptor splice site variants typically lead to a loss of protein function (PMID: 16199547), and loss-of-function variants in VPS13B are known to be pathogenic (PMID: 15141358, 16648375, 20461111). 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 is reported to be combination with another VPS13B variant in an individual with features consistent with Cohen syndrome (Invitae). This variant is not present in population databases (ExAC no frequency). This sequence change affects a donor splice site in intron 40 of the VPS13B gene. It is expected to disrupt RNA splicing and likely results in an absent or disrupted protein product.
