Description

This sequence change affects an acceptor splice site in intron 9 of the COL4A5 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), and loss-of-function variants in COL4A5 are known to be pathogenic (PMID: 9195222, 10752524, 14514738, 24854265, 26809805). This variant is not present in population databases (gnomAD no frequency). Disruption of this splice site has been observed in individuals with Alport syndrome (PMID: 11462238, 20378821). This variant is also known as c.749-1G>A. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. For these reasons, this variant has been classified as Pathogenic.
