Description

This sequence change affects an acceptor splice site in intron 9 of the SLC26A4 gene. It is expected to disrupt RNA splicing and likely results in an absent or disrupted protein product. This variant is not present in population databases (ExAC no frequency). This variant has been observed in individual(s) with Pendred syndrome (PMID: 18250610). In at least one individual the data is consistent with the variant being in trans (on the opposite chromosome) from a pathogenic variant. It is also known as IVS9-1G>A in the literature. 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. Donor and acceptor splice site variants typically lead to a loss of protein function (PMID: 16199547), and loss-of-function variants in SLC26A4 are known to be pathogenic (PMID: 16283880, 25394566, 26252218, 26445815). For these reasons, this variant has been classified as Pathogenic.
