Sarah Pantaleo gene: CFAP20 was added gene: CFAP20 was added to Retinitis pigmentosa_Autosomal Recessive/X-linked. Sources: Literature Mode of inheritance for gene: CFAP20 was set to BIALLELIC, autosomal or pseudoautosomal Publications for gene: CFAP20 were set to PMID:36329026 Phenotypes for gene: CFAP20 were set to Retinitis pigmentosa (MONDO:0019200) Review for gene: CFAP20 was set to GREEN Added comment: CFAP20 is a ciliopathy candidate. Demonstrate in zebrafish that cfap20 is required for motile cilia function, and in C. elegans, CFAP-20 maintains the structural integrity of non-motile cilia inner junctions, influencing sensory-dependent signalling and development. Human patients and zebrafish with CFAP20 mutations both exhibit retinal dystrophy (retinitis pigments). Hence, CFAP20 functions within a structural./functional hub centred on the inner junction that is shared between motile and non-motile cilia, and is distinct from other ciliopathy-associaetd domains or macromolecular complexes. Describe 8 individuals from 4 independent families with damaging biallelic variants (homozygous or compound heterozygous) in CFAP20 that segregate with retinal dystrophy. All variants cluster to one side of the protein, with two of the residues directly contacting alpha-tubullin. Family 1 - consanguineous set of 3 siblings from Sudan, homozygous for CFAP20 c.305G>A; p.Arg102His (they also had a homozygous variant in DYNC1LI2 however CFAP20 was considered the better candidate. Family 2 - 3 siblings from Spain, 2 with retinal dystrophy, 1 genetically tested and has c.337C>T; p.(Arg113Trp) and c.397delC; p.(Gln133Serfs*5) Family 3 - single affected family member compound het for c.164+1G>A and c.457A>G; p.(Arg153Gly). Family 4 - 3 affected siblings with generalised retinopathy and variable neurological deficits with c.164+1G>A and c.257G>A; p.(Tyr86Cys) For all families, no individuals had signs of polycystic kidney disease; however, not all individuals had kidney imaging. Visual defecit phenotype presented between adolescence and adulthood (17-56 years old). Used HEK293T cell expression studies to demonstrate a statistically significant decline of mutated CFAP20 protein levels (with the exception of p.Arg102His). To test the specific variants, they used the C.elegans orthologues. Sources: Literature |
