Description

This sequence change creates a premature translational stop signal (p.Arg329*) in the AHI1 gene. It is expected to result 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 Joubert syndrome (PMID: 18054307, 21937992). ClinVar contains an entry for this variant (Variation ID: 30760). Loss-of-function variants in AHI1 are known to be pathogenic (PMID: 15322546, 16453322). For these reasons, this variant has been classified as Pathogenic.
