Description

For these reasons, this variant has been classified as Pathogenic. This variant has not been reported in the literature in individuals with COL4A5-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change creates a premature translational stop signal (p.Trp20Alafs*17) in the COL4A5 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in COL4A5 are known to be pathogenic (PMID: 9195222, 10752524, 14514738, 24854265, 26809805).
