I don't know

PMID: 24886560 - 2 unrelated patients with mild Joubert syndrome patients found (1 hom missense, 1 chet inframe deletion/missense). Authors suggest biallelic null variants are lethal. PMID: 21493627 - 1 fetus with Meckell syndrome and chet for a splice/gene deletion. The splice variant proven to result in exon skipping -> PTC, but the deletion spans a large region including 18 other genes. Patient also had an additional variant in CEP290 called LP. Authors perform functional studies on patient cells but given the large deletion/CEP290 variant i dont see the results are usable PMID: 25920555 - another report of digenic inheritance - not usable, patient was only heterozygous for a single B9D1 variant Summary: 2 unrelated patients, AMBER
