Invitae RCV000554746 SCV000634557 pathogenic Familial aplasia of the vermis 2021-05-22 criteria provided, single submitter clinical testing This variant results in the deletion of exon 7 and part of exon 8 (c.749+528_1062del) of the AHI1 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 AHI1 are known to be pathogenic (PMID: 15322546, 16453322, 28442542, 29186038). This variant has been observed in individual(s) with Joubert syndrome (Invitae). This variant disrupts the p.Arg351 amino acid residue in AHI1. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 26092869, 23532844). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. For these reasons, this variant has been classified as Pathogenic.
